Analyst readout for executives and security teams
Plain-English summary
CVE-2010-1919 is a remote denial-of-service issue in EMC Avamar. A crafted TCP message can cause the gsan service to hang, potentially disrupting backup or recovery operations. The provided sources do not describe data theft or code execution.
Executive priority
Treat as a backup resilience risk. It is not evidenced as actively exploited, but a service hang in backup infrastructure can affect recovery readiness and incident response confidence.
Technical view
The CVE describes an unspecified vulnerability affecting EMC Avamar 4.1.x and 5.0 before SP1. Remote attackers can trigger a gsan service hang via a crafted TCP message. The source bundle provides no CVSS, CWE, protocol detail, or exploit telemetry.
Likely exposure
Exposure is likely limited to organizations still running EMC Avamar 4.1.x or 5.0 before SP1, especially where Avamar services are reachable from untrusted networks or broad internal segments.
Exploitation context
The provided sources do not show active exploitation, and CISA KEV status is false. The vulnerability is remotely reachable over TCP, but the public details in the bundle are sparse and do not include exploit mechanics.
Researcher notes
The vulnerability is unspecified beyond a crafted TCP message causing gsan to hang. Avoid assuming root cause, affected ports, or exploitability beyond denial of service. Primary research should focus on vendor advisory details and authenticated asset/version validation.
Mitigation direction
- Identify all EMC Avamar deployments and exact versions.
- Upgrade Avamar 5.0 systems to SP1 or later where vendor guidance confirms applicability.
- Check EMC advisory ESA-2010-007 for supported fixes for 4.1.x.
- Restrict network access to Avamar services to trusted backup management paths.
- Monitor gsan service health for hangs, crashes, or unexpected restarts.
Validation and detection
- Confirm whether any Avamar 4.1.x or 5.0 pre-SP1 systems remain in service.
- Review network exposure for Avamar TCP services from untrusted segments.
- Check backup job failures around gsan hangs or restarts.
- Verify installed service pack level against EMC advisory ESA-2010-007.
- Confirm compensating firewall rules are active and documented.
