In general, to fix clear-text logging of sensitive information, remove sensitive values from log messages or replace them with non-sensitive representations (such as static descriptions, redacted tokens, or irreversible hashes where operationally necessary). The goal is to preserve enough context for debugging/operations without exposing secret material or identifiers that might be considered sensitive.

For this specific file, the best fix with minimal functional impact is:

• Stop logging secret_name and retrieved_secret.name in clear text.
• Keep the log messages, but replace the dynamic secret identifier with a redacted placeholder or a generic description, while still logging non-sensitive context like the key vault name.
• Do not change how secrets are retrieved or stored; only adjust the log messages.

Concretely:

• In get_keyvault_secret, change the log at line 42 from "Retrieving secret {} from {}.".format(secret_name, self.keyvault_name) to a message that does not include secret_name, e.g. "Retrieving secret from key vault '%s'." % self.keyvault_name.
• In get_keyvault_secret, change the log at line 45 from "Retrieved secret value for {}.".format(retrieved_secret.name) to something like "Retrieved secret value from key vault '%s'." % self.keyvault_name.
• In set_keyvault_secret, change the log at line 60 from "Creating or updating a secret '{}'.".format(secret_name) to a generic message without the name, e.g. "Creating or updating a secret in key vault '%s'." % self.keyvault_name, and similarly at line 62.

No new imports or methods are required; only the string formatting of existing logging calls needs to be adjusted.

In general, to fix “empty except” issues, either (a) replace them with explicit condition checks that avoid raising the exception in the first place, or (b) add appropriate handling such as logging, re‑raising, or compensating actions, and document that ignoring is intentional if that is truly desired.

Here, the best fix that preserves existing functionality is to avoid raising IndexError at all by checking the row length before accessing each optional column. This keeps the behavior (“if column is missing, do nothing”) identical, but removes the need for try/except entirely. To make the code self‑documenting, we can add a brief comment indicating these are optional columns which may not be present in all rows. Concretely, in Solutions/CiscoUmbrella/Data Connectors/ciscoUmbrellaDataConn/__init__.py, in the region after the event = { ... } dict is created (lines 849–880), replace each try: event[...] = row[N]; except IndexError: pass with an if len(row) > N: conditional assignment. No new imports are required, and existing logging remains untouched.

Generally, the right fix is to avoid using empty except blocks. Instead, either (a) prevent the exception by checking bounds before accessing row[index], or (b) handle the exception in a meaningful way (e.g., logging or adding a comment to document why it is safe to ignore).

Here, we want to preserve existing behavior: if the row does not have that index, simply don’t add that key to event. The cleanest change without altering functionality is to replace each try/except IndexError: pass with a conditional that only reads row[index] when it exists. This removes the empty except and makes the intent clear. Concretely, in Solutions/CiscoUmbrella/Data Connectors/ciscoUmbrellaDataConn/__init__.py around the shown snippet, for each block like:

try:
    event['transaction id'] = row[30]
except IndexError:
    pass

we should replace it with:

if len(row) > 30:
    event['transaction id'] = row[30]

and similarly for all subsequent optional fields (indices 31–38). No new imports or helper methods are required; we just use len(row) checks. This maintains the same behavior (field present only if the column exists) while satisfying CodeQL by removing the empty except blocks.

In general, to fix empty except blocks, either remove the try/except by guarding the code (e.g., checking length before indexing), or add appropriate handling: logging, re‑raising, or otherwise acting on the exception. For cases where ignoring the exception is genuinely intended, add a clear comment explaining why, and optionally log at debug level.

Here, all the try/except IndexError: pass blocks are doing the same thing: “if this column exists, add it to event; otherwise, skip it.” We can preserve that behavior while avoiding empty except blocks by replacing each try/except with an index‑range guard: if len(row) > N: event['field'] = row[N]. This keeps the functionality (missing columns are simply not set) but removes exception‑based control flow and the empty handlers.

Concretely, in Solutions/CiscoUmbrella/Data Connectors/ciscoUmbrellaDataConn/__init__.py, in the region starting around line 881 where event is built from row, replace each try/except IndexError: pass pair for indices 30 through 56 with a simple if len(row) > index: assignment. No new imports or helper methods are required; everything uses existing variables (row, event) and standard Python operations.

To fix the problem, we should stop using empty except IndexError: pass blocks for optional CSV fields and instead guard access to row[...] with an index check. This preserves the existing behavior (if the column is missing, the field is simply not added to event) while removing silent exception handling and making the code’s intent clearer.

Concretely, in Solutions/CiscoUmbrella/Data Connectors/ciscoUmbrellaDataConn/__init__.py, in the method that builds event from row, replace each try block that assigns from a particular index with a conditional if len(row) > N: before the assignment, for indices 30 through 36 (and any further ones in the omitted section, if present in the same pattern). No new imports are required because we only use basic Python operations. The rest of the logic in the method and file remains unchanged.

In general, the issue should be fixed by avoiding empty except blocks. Instead of relying on exceptions for control flow and then ignoring them, the code should explicitly check conditions that might fail (here, the row length) before accessing elements, or otherwise record that data is missing (e.g., set a default value). This preserves current behavior (no exception raised for short rows) but removes the silent swallowing of errors.

The best way to fix this specific case without changing functionality is to replace each try/except IndexError: pass block with a simple length check before assigning the column to the event dict. For instance, instead of:

try:
    event['Traffic Source'] = row[30]
except IndexError:
    pass

we check:

if len(row) > 30:
    event['Traffic Source'] = row[30]

Functionally this is the same: if the index is out of range, we simply skip setting that key. However, we no longer use exceptions as control flow and no longer have an empty except block. We should apply this to all the optional columns at indices 30–36. No new imports or helper methods are required; we only update the body of parse_csv_cdfw where these lines occur.

Concretely, in Solutions/CiscoUmbrella/Data Connectors/ciscoUmbrellaDataConn/__init__.py, within the parse_csv_cdfw method around lines 706–733, replace each try/except IndexError: pass sequence with an if len(row) > index: guard assigning the value. The rest of the method and file remains unchanged.

In general, unused local variables should either be removed or renamed to a clearly "unused" name (such as _ or unused_base_url) if they are intentionally there for documentation. Here, the variable base_url is calculated but not used at all, and the rest of the logic (building response and returning the HTTP response) does not depend on it. Therefore, the best fix without changing existing functionality is to delete the base_url assignment line.

Concretely, in Solutions/AWS Systems Manager/Playbooks/CustomConnector/AWS_SSM_FunctionAppConnector/GetInventory/__init__.py, remove line 100:

base_url = req.url.split('?')[0]

No new methods, imports, or definitions are needed, and no other code in the snippet needs adjustment. This will eliminate the unused variable and the CodeQL warning while preserving the current behavior (which already returns "nextLink": None).

In general, the problem is fixed by avoiding empty except blocks: either prevent the exception using explicit checks (e.g., check the row length before indexing) or handle it meaningfully (typically by logging a warning or debug message). For expected/optional missing fields, it’s better to use simple bounds checks or default values rather than catching IndexError. For data conversion, we should narrow the exception type and log failures, so that only bad input is caught and not unrelated bugs.

The best low-impact fix here is:

• For the optional CSV columns (row[48] through row[54]), remove the try/except IndexError and instead check len(row) before accessing each index. This preserves behavior (fields are only set when available) but removes the empty except and makes the logic clearer.
• For the integer conversion loop, restrict the exception to ValueError and TypeError, and log a message when conversion fails instead of silently passing. This keeps behavior similar (field remains unconverted if invalid) while making failures visible.

Concretely, in Solutions/CiscoUmbrella/Data Connectors/ciscoUmbrellaDataConn/__init__.py:

• Replace the series of try: event['...'] = row[XX] except IndexError: pass between lines ~523–553 with conditional assignments such as if len(row) > 48: event['Organization ID'] = row[48], etc. We already have access to row, and len(row) is cheap.
• Update the for field in int_fields: block so that the except catches ValueError and TypeError, and logs using the existing logging module (already imported at line 3). For example: logging.debug("Failed to convert %s to int: %r", field, event.get(field)). This does not change output structure but adds observability.

No new imports are needed; we can reuse the existing logging import.

In general, an "empty except" should either be replaced by more specific handling (logging, default values, clean fallback) or be documented with a clear comment explaining why it is safe to ignore. For this code, the best non‑breaking fix is to retain the behavior of skipping missing optional fields while adding debug‑level logging to record that an IndexError occurred. Likewise, for the integer conversion loop, we can log when a conversion fails but still keep the existing behavior of leaving the field unset or non‑integer.

Concretely, in Solutions/CiscoUmbrella/Data Connectors/ciscoUmbrellaDataConn/__init__.py, within the shown region around lines 521–564, we should replace the except IndexError: pass blocks with except IndexError as e: blocks that emit a logging.debug message mentioning the field name and index. For the except Exception: pass around int(event[field]), we should catch as Exception as e and log a debug message indicating which field failed to convert and why. This uses the already‑imported logging module, requires no new imports, and does not change functional behavior because failures were previously ignored entirely; now they are still ignored but recorded.

In general, to fix empty except blocks, the handler should either (1) log the exception, (2) take corrective action (e.g., set a default value), or (3) explicitly document why it is safe to ignore the exception. Here we want to preserve the existing behavior that missing columns do not break ingestion, while avoiding a bare pass.

The best approach with minimal functional change is: when an IndexError happens (i.e., the CSV row is shorter than expected), explicitly set the corresponding event field to None (or some sentinel like an empty string) instead of doing nothing. This keeps downstream behavior similar (field may be absent or "falsey") but is clearer and removes the empty handler. Alternatively, we could simply add a comment explaining intentional ignore; however, improving the behavior slightly by assigning None is more robust and still consistent with treating these fields as optional. No new imports are required; we only modify the except IndexError bodies in the provided region of Solutions/CiscoUmbrella/Data Connectors/ciscoUmbrellaDataConn/__init__.py.

Concretely, for each block:

try:
    event['Detected Response File Type'] = row[46]
except IndexError:
    pass

we will change it to:

try:
    event['Detected Response File Type'] = row[46]
except IndexError:
    event['Detected Response File Type'] = None

and do the same for the surrounding fields (Warn Categories, Organization ID, Application Entity Name, Application Entity Category, Egress IP, AI Model Name, AI Supply Chain Categories, Event correlation ID). This eliminates empty except blocks without altering control flow or adding dependencies.

General approach: Avoid using ${{ ... }} expressions that embed user-controlled values directly inside run: shell scripts. Instead, assign the untrusted value to an environment variable using workflow expression syntax, and then reference it using native shell variable expansion ($VAR) within the script.

Concrete fix here: For the “Commit updated bundles” step, move ${{ github.event.pull_request.head.ref }} into a new env variable (e.g., PR_HEAD_REF) and then change the git push line to use $PR_HEAD_REF. This prevents GitHub from interpolating the untrusted value into the shell script; the shell now receives the value as normal data via the environment, which is the recommended pattern. Functionality remains identical because git push origin <branch> is the same call; we’re only changing how the branch name gets passed in.

Changes needed in .github/workflows/aws-s3-bundle-update.yaml:

• In the “Commit updated bundles” step (lines 77–106), add an environment variable, e.g.:

  env:
    GITHUB_TOKEN: ${{ steps.generate_token.outputs.token }}
    PR_HEAD_REF: ${{ github.event.pull_request.head.ref }}

• Update line 101 from:

  git push origin ${{ github.event.pull_request.head.ref }}

  to:

  git push origin "$PR_HEAD_REF"

No additional imports or external dependencies are needed.
