Analysis

Impact

A vulnerability in HPE NonStop CIPSAM permits an out‑of‑bounds write that can corrupt buffer data, potentially compromising the integrity of system memory and the reliability of CIPSAM functionality.

Affected Systems

The affected system is Hewlett Packard Enterprise's NonStop CIPSAM component. No specific product versions are listed in the CNA data, so all deployments of CIPSAM remain potentially vulnerable until a patch is applied.

Risk and Exploitability

The CVSS score of 8.7 indicates high severity. EPSS data is not available, and the vulnerability is not listed in CISA’s KEV catalog. The likely attack vector is local execution on systems where the attacker can interact with CIPSAM; the nature of the out‑of‑bounds write suggests that an attacker could manipulate memory to cause application errors or potentially take control, but no specific exploitation path is documented in the input.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
