EPSS estimates a 1% chance of exploitation within 30 days, higher than 63% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of cososys_endpoint_protector you run against the affected versions below, and install the vendor's latest release.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
Netwrix CoSoSys Endpoint Protector through 5.9.3 and CoSoSys Unify through 7.0.6 contain a remote code execution vulnerability in the logging component of the Endpoint Protector and Unify server application which allows an unauthenticated remote attacker to send a malicious request, resulting in the ability to execute system commands with root privileges.

The underlying weakness: Logging of Excessive Data
The product logs too much information, making log files hard to process and possibly hindering recovery efforts or forensic analysis after an attack.
How developers prevent this class of flaw
- Suppress large numbers of duplicate log messages and replace them with periodic summaries. For example, syslog may include an entry that states last message repeated X times when recording repeated events.
- Support a maximum size for the log file that can be controlled by the administrator. If the maximum size is reached, the admin should be notified. Also, consider reducing functionality of the product. This may result in a denial-of-service to legitimate product users, but it will prevent the product from adversely impacting the entire system.
- Adjust configurations appropriately when the product is transitioned from a debug state to production.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: yes, technical impact: total).
- Record last changed materially (score, affected products, status or references).
