CVE-2023-24482
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 · uneditedA vulnerability has been identified in COMOS V10.2 (All versions), COMOS V10.3.3.1 (All versions < V10.3.3.1.45), COMOS V10.3.3.2 (All versions < V10.3.3.2.33), COMOS V10.3.3.3 (All versions < V10.3.3.3.9), COMOS V10.3.3.4 (All versions < V10.3.3.4.6), COMOS V10.4.0.0 (All versions < V10.4.0.0.31), COMOS V10.4.1.0 (All versions < V10.4.1.0.32), COMOS V10.4.2.0 (All versions < V10.4.2.0.25). Cache validation service in COMOS is vulnerable to Structured Exception Handler (SEH) based buffer overflow. This could allow an attacker to execute arbitrary code on the target system or cause denial of service condition.
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 confidenceSEH-based buffer overflow in COMOS cache validation service allows remote attackers to execute arbitrary code or cause denial of service. The vulnerability affects multiple COMOS V10.x versions across 10.2 through 10.4.2.0.

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 COMOS installationLocate Siemens COMOS installation on the system. Check Program Files directories or look for COMOS-related executables and services.Affected if COMOS software is present on the system
-
Identify COMOS versionRetrieve the installed COMOS version number from the system. This is typically found in the product's about dialog, installed programs list, or version information embedded in COMOS executables.Affected if The version falls within any of these ranges: 10.2 to 10.3.3.1.44, 10.3.3.2 to 10.3.3.2.32, 10.3.3.3 to 10.3.3.3.8, 10.3.3.4 to 10.3.3.4.5, 10.4.0.0 to 10.4.0.0.30, 10.4.1.0 to 10.4.1.0.31, or 10.4.2.0 to 10.4.2.0.24
-
Verify cache validation service presenceCheck if the COMOS cache validation service is installed and running. This service is the specific component vulnerable to the SEH-based buffer overflow.Affected if The cache validation service is enabled and accessible on the system
-
Compare version against fixed releasesConfirm whether the installed version is lower than the first fixed version in the user's specific release line. For example, if using 10.4.x, check if version is below 10.4.2.0.25.Affected if The installed version is lower than the corresponding fixed version for that release branch
The system is affected if Siemens COMOS is installed with a version that falls within any of the affected version ranges AND the cache validation service is present and enabled.

Apply vendor-supplied patches: upgrade to V10.3.3.1.45, V10.3.3.2.33, V10.3.3.3.9, V10.3.3.4.6, V10.4.0.0.31, V10.4.1.0.32, or V10.4.2.0.25 or later. Network segmentation and restricting exposure of the cache validation service can provide additional mitigation.
Upgrade to the minimum fixed version for your current branch: V10.3.3.1.45, V10.3.3.2.33, V10.3.3.3.9, V10.3.3.4.6, V10.4.0.0.31, V10.4.1.0.32, or V10.4.2.0.25 depending on your branch
- 1. Identify the current COMOS version by checking the product 'About' information or installation details
- 2. Determine which version branch your installation belongs to (10.2.x, 10.3.3.1.x, 10.3.3.2.x, 10.3.3.3.x, 10.3.3.4.x, 10.4.0.0.x, 10.4.1.0.x, or 10.4.2.0.x)
- 3. For COMOS V10.2: Upgrade to V10.3.3.1.45 or later (or migrate to a later supported branch)
- 4. For COMOS V10.3.3.1.x: Upgrade to V10.3.3.1.45 or later
- 5. For COMOS V10.3.3.2.x: Upgrade to V10.3.3.2.33 or later
- 6. For COMOS V10.3.3.3.x: Upgrade to V10.3.3.3.9 or later
- 7. For COMOS V10.3.3.4.x: Upgrade to V10.3.3.4.6 or later
- 8. For COMOS V10.4.0.0.x: Upgrade to V10.4.0.0.31 or later
