Required Action (CISA)

Apply updates per vendor instructions.

Risk Analysis

This vulnerability in Cisco Secure Access Control System (ACS) involves insecure Java deserialization, allowing an unauthenticated, remote attacker to execute arbitrary commands. While a CVSS score is not available, its HIGH severity and inclusion in CISA's KEV catalog with an EPSS score of 0.04024 indicate a significant risk of exploitation.

This vulnerability is actively being exploited in the wild, as confirmed by its presence in CISA's KEV catalog. It is remotely exploitable without authentication.

Recommended Action

Update Cisco Secure Access Control System (ACS) to a patched version. Implement network segmentation and access controls to limit exposure of management interfaces.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2018-0147 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

CISA has added CVE-2018-0147 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
