Stack Buffer Overflow in Dell PowerProtect Restore Agent

Dell PowerProtect Data Manager versions 20.2.0.0 and below contain a stack buffer overflow vulnerability in the file-level restore agent component. This high-severity flaw (CVSS 7.8) allows a high-privileged remote attacker to trigger memory corruption, potentially leading to information disclosure and lateral movement within backup infrastructure. Organizations relying on PowerProtect for data protection and recovery are at risk, as the restore agent typically operates with elevated permissions and access to sensitive backup data. The vulnerability is particularly critical because backup systems are frequent targets in ransomware and data exfiltration campaigns, making this an attractive vector for attackers seeking to compromise protected data.

While this CVE does not currently map to specific MITRE ATT&CK techniques in the framework, Casky's 754 security skills—powered by Claude AI's extended reasoning—would detect exploitation attempts through behavioral analysis of memory corruption patterns, abnormal restore agent process execution, and unauthorized data access. Practitioners using Casky would identify suspicious indicators such as: unusual restore job parameters designed to overflow buffers, unexpected privilege escalation from the restore agent process, anomalous inter-process communication patterns, and data staging activities inconsistent with legitimate restore operations. The platform's skill-based detection would flag these attack precursors before successful exploitation, enabling defenders to patch Dell PowerProtect systems and monitor restore agent behavior for signs of compromise.
