CVE-2016-6025
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 · uneditedThe Configuration Manager in IBM Sterling Secure Proxy (SSP) 3.4.2 before 3.4.2.0 iFix 8 and 3.4.3 before 3.4.3.0 iFix 1 allows remote attackers to obtain access by leveraging an unattended workstation to conduct a post-logoff session-reuse attack involving a modified URL.
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 confidenceThe Configuration Manager in IBM Sterling Secure Proxy fails to properly invalidate user sessions after logout. An attacker with physical access to an unattended workstation can use a modified URL to reuse a still-active session and gain unauthorized access to the application after the legitimate user has logged off.

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 installed IBM Sterling Secure Proxy versionRun 'java -version' or check the product's about/version information panel in the Configuration Manager GUI, or inspect the installation directory for version files. Typical path: <install_dir>/bin/version.sh or check the installedPackages file in the configuration directory.Affected if The installed version is exactly 3.4.2.0 or exactly 3.4.3.0
-
Confirm Configuration Manager component is deployedVerify the IBM Sterling Secure Proxy Configuration Manager web application is accessible. Check if the '/ConfigManager' or similar admin endpoint is exposed and operational on the affected host.Affected if Configuration Manager web interface is accessible and the product version is 3.4.2.0 or 3.4.3.0
-
Test session invalidation behaviorLog into Configuration Manager, note the session identifier or cookie, then log out. Attempt to access a protected page using the original session URL or cookies without re-authenticating.Affected if After clicking logout, the prior session URL or cookies still grant access to authenticated functions without requiring new credentials
-
Check IBM fix levelReview installed iFixes by running 'lslpp -l' on AIX, 'rpm -qa' on Linux, or checking the fix history in the Configuration Manager under System Administration > Maintenance. Look for iFix 8 for v3.4.2 or iFix 1 for v3.4.3.Affected if The system is at version 3.4.2.0 or 3.4.3.0 with no corresponding iFix installed
A user is affected if their IBM Sterling Secure Proxy version is exactly 3.4.2.0 or 3.4.3.0 AND the Configuration Manager is in use AND sessions remain valid after logout without the corresponding IBM iFix applied.

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 dataApply IBM iFix 8 for version 3.4.2 or iFix 1 for version 3.4.3 as specified by IBM. Additionally, enforce workstation auto-lock policies and instruct users to explicitly close browsers after logout to mitigate the physical access attack vector.
