Published: May 4, 2022
Official Description
The TLS and DTLS implementations in OpenSSL do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information.
CISA KEV Advisory
OpenSSL Information Disclosure Vulnerability
The TLS and DTLS implementations in OpenSSL do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information.
Apply updates per vendor instructions.
Risk Analysis
This vulnerability, known as Heartbleed, affects the TLS and DTLS implementations in OpenSSL. It allows remote attackers to obtain sensitive information from memory, including private keys and user data. The very high EPSS score indicates a high likelihood of exploitation, making this a critical vulnerability.
This vulnerability is actively being exploited in the wild and is listed in CISA's KEV catalog, confirming its active exploitation. It is remotely exploitable due to its nature in handling network packets.
Update OpenSSL to a patched version immediately. After patching, regenerate all private keys and re-issue certificates that were used with the vulnerable OpenSSL versions. Force users to change passwords.
Technical Analysis
CVE-2014-0160 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-2014-0160 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.
