CVE-2024-48852
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedInsertion of Sensitive Information into Log File vulnerability observed in FLEXON. Some information may be improperly disclosed through https access. This issue affects FLXEON through <= 9.3.4.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceFLEXON through version 9.3.4 contains an information disclosure vulnerability where sensitive information transmitted over HTTPS connections is being improperly written to log files. This allows potentially sensitive data such as authentication credentials, session tokens, or other confidential content to be exposed in log storage.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify FLEXON installation and versionLocate the FLEXON installation directory and check for version information files (such as a version.txt, about dialog, or the executable's properties). Compare the found version to the affected range: any version through 9.3.4 is potentially vulnerable.Affected if FLEXON version is 9.3.4 or earlier
-
Confirm logging is enabledExamine FLEXON's configuration files or settings interface for logging-related options. Look for any setting that enables logging, debug output, or diagnostic file creation.Affected if Logging or diagnostic output is turned on
-
Locate log filesSearch the FLEXON installation directory and any configured log output directories for files with extensions such as .log, .txt, or similar log file formats commonly used by the application.Affected if Log files exist in the FLEXON environment
-
Inspect log contents for sensitive dataOpen log files and search for patterns indicating HTTPS-related sensitive information such as authorization headers, session tokens, credentials, or other HTTPS-transmitted data that should not be recorded.Affected if Log files contain HTTPS request headers, authentication tokens, or other confidential data
A user is affected if FLEXON version 9.3.4 or earlier is installed, logging is enabled, and log files contain sensitive HTTPS-transmitted data such as authentication credentials or session tokens.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataIdentify and remediate all code paths where sensitive data (credentials, tokens, headers, cookies) transmitted over HTTPS are being logged. Implement proper log sanitization to exclude sensitive fields, and audit existing logs for any exposed credentials requiring rotation.
