Management Pack for Microsoft System Center: Relative Path Traversal
CVE-2026-107239 is a high-severity relative path traversal vulnerability in Management Pack for Microsoft System Center from Veeam, with a CVSS 4.0 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. The record lists version 13.1.0.334 as the first without the flaw, so updating Management Pack for Microsoft System Center to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.65% chance of exploitation within 30 days, higher than 52% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Management Pack for Microsoft System Center to 13.1.0.334 or a later version.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
A vulnerability allowing a member of the Veeam Virtualization Extensions Users group to perform remote code execution (RCE) on servers running the Veeam Management Pack for Microsoft System Center Collector service.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Relative Path Traversal
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as.. that can resolve to a location that is outside of that directory.
How developers prevent this class of flaw
- Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: total).
- Record last changed materially (score, affected products, status or references).
