The message engine in CA ARCserve Backup r12.0 and r12.0 SP1 for Windows allows remote attackers to cause a denial of service (crash) via (1) an invalid 0x13 message, which is not properly handled in the ASCORE module, or (2) a 0x3B message with invalid stub data that triggers an RPC marshalling error.

Security readout for executives and security teams

CVE-2009-1761 is a remote denial-of-service issue in the CA ARCserve Backup message engine for Windows. A remote attacker could crash the backup message engine by sending malformed messages, potentially interrupting backup operations and recovery readiness. Exposure is most likely where legacy CA ARCserve Backup r12.0 or r12.0 SP1 for Windows remains deployed and reachable over a network. Internet exposure is not stated in the sources and should not be assumed. Treat this as a business-continuity risk for legacy backup infrastructure. Prioritize if affected backup servers support critical recovery workflows or are reachable beyond trusted administration networks. Mitigation focus: Identify any CA ARCserve Backup r12.0 or r12.0 SP1 Windows deployments.; Review CA/Broadcom advisory guidance for vendor-supported fixes or replacement paths.; Restrict network reachability to backup servers and management services..
