ConnectWise has released software updates to address two security flaws in its ScreenConnect remote desktop and access software, including a critical bug that could enable remote code execution on affected systems.

The vulnerabilities, which currently lack CVE identifiers, are listed below –

  • Authentication bypass using an alternate path or channel (CVSS score: 10.0)
  • Improper limitation of a pathname to a restricted directory aka “path traversal” (CVSS score: 8.4)

The company deemed the severity of the issues as critical, citing they “could allow the ability to execute remote code or directly impact confidential data or critical systems.”

Both the vulnerabilities impact ScreenConnect versions 23.9.7 and prior, with fixes available in version 23.9.8. The flaws were reported to the company on February 13, 2024.

While there is no evidence that the shortcomings have been exploited in the wild, users who are running self-hosted or on-premise versions are recommended to update to the latest version as soon as possible.

“ConnectWise will also provide updated versions of releases 22.4 through 23.9.7 for the critical issue, but strongly recommend that partners update to ScreenConnect version 23.9.8,” ConnectWise said.
