CVE-2024-27264
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 · uneditedIBM Performance Tools for i 7.2, 7.3, 7.4, and 7.5 could allow a local user to gain elevated privileges due to an unqualified library call. A malicious actor could cause user-controlled code to run with administrator privilege. IBM X-Force ID: 284563.
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 · high confidenceIBM Performance Tools for i versions 7.2 through 7.5 contain an unqualified library call that can be exploited by a local attacker. By placing a malicious library in a location where the application searches for libraries without a fully qualified path, an unprivileged local user can cause arbitrary code to execute with administrator-level privileges, achieving local privilege escalation.

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.
-
Confirm IBM Performance Tools for i is installedOn the IBM i system, use the command GO CMDPRTF or WRKOBJ to list objects related to Performance Tools. Alternatively, check system-installed licensed programs using DSPLICPGM and look for entries containing 'Performance Tools' or 'PTF' related tools.Affected if The product is present on the system and appears in installed software listings
-
Identify the installed version of IBM Performance Tools for iUse the command DSPPTF to display Program Temporary Fixes and version information. Cross-reference with the base version by examining the installed licensed program details or using WRKOBJ to find version-specific objects.Affected if The installed version is 7.2, 7.3, 7.4, or 7.5 as listed in the affected versions range
-
Examine the library search path configurationOn IBM i, review the library list (LIBLE) that the Performance Tools application uses. Check the system library list and any application-specific library lists using WRKLIBL or DSPJOB to view the current library list in use when the tool runs.Affected if Directories or libraries in the search path are writable by unprivileged users, allowing them to place malicious library files
-
Check file system permissions on directories in the library search pathUse the command WRKAUT or DSP-aut to check object authorities on each directory or library in the Performance Tools search path. Identify directories where unprivileged users have write (*WRITE) or add (*ADD) authority.Affected if Any directory in the library search path allows write access to unprivileged (non-administrator) users, enabling library injection
-
Verify if unprivileged users can inject librariesAttempt to create a test library or object in the directories identified in the library search path using a non-privileged user profile. Alternatively, document which user profiles have write authority to each path.Affected if Unprivileged users can create or add objects to directories that the application searches during library loading
A user is affected if IBM Performance Tools for i version 7.2 through 7.5 is installed AND unprivileged users have write access to any directory in the application's library search path, enabling library preloading exploitation.

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 the IBM PTF (Program Temporary Fix) for this vulnerability when released. Until then, restrict file system permissions to prevent unprivileged users from writing to directories in the application library search path.
