CVE-2024-1708 ConnectWise CVE debrief

CVE-2024-1708 is a ConnectWise ScreenConnect path traversal vulnerability that CISA has listed in its Known Exploited Vulnerabilities catalog. That KEV inclusion means CISA considers the issue known to be exploited in the wild and has set a remediation due date of 2026-05-12 for the public sector. The safest response is to apply vendor-recommended mitigations immediately; if mitigations are not available for a given deployment, CISA’s guidance is to discontinue use of the product.

Who should care

Organizations using ConnectWise ScreenConnect, especially internet-facing or externally accessible deployments, should treat this as high priority. Federal agencies and other environments that follow CISA KEV/BOD-style remediation timelines should act before the 2026-05-12 due date. MSPs and IT teams managing ScreenConnect for multiple clients should check every instance, including hosted and self-managed deployments.

Technical summary

The available source corpus identifies the issue as a path traversal vulnerability in ConnectWise ScreenConnect. CISA’s KEV listing indicates the vulnerability has been exploited in the wild, but the provided corpus does not include deeper exploit mechanics or version-by-version technical detail. Because the vendor advisory content is not included in the supplied sources, defensive guidance should be limited to the KEV-required action: apply vendor mitigations, follow applicable BOD 22-01 guidance for cloud services, or discontinue use if mitigation is unavailable.

Defensive priority

Critical. CISA has placed CVE-2024-1708 in the Known Exploited Vulnerabilities catalog, which signals active exploitation and a need for urgent remediation.

Recommended defensive actions

  • Identify all ConnectWise ScreenConnect instances, including hosted, cloud, and self-managed deployments.
  • Apply the vendor’s mitigations or updates referenced by CISA as soon as possible.
  • If mitigations are unavailable for a deployment, discontinue use of the product until a supported fix is available.
  • For federal cloud-service use cases, follow applicable BOD 22-01 guidance.
  • Validate that remediation was completed before the CISA KEV due date of 2026-05-12.
