A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

Is CVE-2014-0160 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2014-0160 (OpenSSL Information Disclosure Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2022-05-04. CISA required all US federal civilian agencies to remediate this vulnerability by 2022-05-25. The required action was: Apply updates per vendor instructions. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

What type of vulnerability is CVE-2014-0160?

CVE-2014-0160 is classified as Out-of-bounds Read (CWE-125). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description

The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to d1_both.c and t1_lib.c, aka the Heartbleed bug.

Exploits & PoCs

Research use only. For defensive security, authorized penetration testing, and academic research only. Never execute exploit code against systems without explicit written authorization.
