CVE-2024-5623
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 · uneditedAn untrusted search path vulnerability in B&R APROL <= R 4.4-00P3 may be used by an authenticated local attacker to get other users to execute arbitrary code under their privileges.
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 confidenceAn untrusted search path vulnerability exists in B&R APROL <= R 4.4-00P3 where an authenticated local attacker can manipulate the executable/library search path to cause other users to inadvertently execute malicious code when running legitimate APROL commands. This path hijacking allows privilege escalation by tricking higher-privileged users into running attacker-controlled code.

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 APROL versionLocate the APROL installation directory and check version information in version files, About dialogs, or the product documentation for your installed version. Common locations include the main APROL installation folder or system information panels.Affected if The installed version is r4.4-00p3 or any earlier version (r4.4-00p2, r4.4-00p1, r4.3, etc.)
-
Check write permissions on APROL application directoriesReview file system permissions on the APROL installation directories and subdirectories. Use OS-native permission checking tools or scripts to enumerate which users have Write or Modify access to folders containing APROL executables and libraries.Affected if Any untrusted or low-privilege authenticated user has Write access to directories where APROL binaries or libraries reside
-
Verify PATH environment variable usage for APROL commandsExamine how APROL commands are launched in your environment. Check if they are invoked using full absolute paths or if they rely on the system PATH environment variable to locate executables. Review any shortcuts, scripts, or automation that invoke APROL utilities.Affected if APROL executables are launched without specifying absolute paths and the system PATH includes directories writable by untrusted users
-
Audit for unauthorized executables in APROL directoriesInspect the APROL installation directories for any unexpected or unauthorized executable files, DLLs, or scripts that were not installed as part of the official APROL release. Compare against a known-good baseline or documentation of expected files.Affected if Unexpected executables or DLLs are present in APROL binary directories, especially with recent modification dates or belonging to untrusted users
You are affected if your APROL version is r4.4-00p3 or earlier AND untrusted users have Write access to any directory in the executable search path used by APROL commands.

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 dataRestrict write access to application directories and ensure APROL executables are launched using absolute paths rather than relying on PATH resolution. If a patch is available from B&R, apply it immediately.
