CVE-2023-2917: Rockwell Automation ThinManager Thinserver Software Vulnerable to Input Validation Vulnerability

Noroxi assessment

Priority: This week (action score 61/100)

  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 72.1% (FIRST EPSS); higher than 99.4% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • According to the record, no fixed version is available yet.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Don’t wait for the next maintenance window. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

The Rockwell Automation Thinmanager Thinserver is impacted by an improper input validation vulnerability.  Due to an improper input validation, a path traversal vulnerability exists, via the filename field, when the ThinManager processes a certain function. If exploited, an unauthenticated remote attacker can upload arbitrary files to any directory on the disk drive where ThinServer.exe is installed.  A malicious user could exploit this vulnerability by sending a crafted synchronization protocol message and potentially gain remote code execution abilities.
