Heartbleed, the OpenSSL memory leak, with CVSS v2 5.0 and v3.1 7.5, a CISA KEV entry and an NVD impact note.

Example 1 of 7 in **Well-Known CVEs** · [Vulnerability Detail Examples](/reference/vulnerability/detail/examples/) · endpoint: [Detail](/reference/vulnerability/detail/)

Tags: `param` `cve` · `value` `CVE-2014-0160`

Asks for `CVE-2014-0160`, the OpenSSL heartbeat bug that leaked server memory.

## What to Notice

- `metrics` has a CVSS v2 score (5.0) and two CVSS v3.1 scores (7.5): a `Primary` one from the NVD and a `Secondary` one from another source. `enrichment.vdeep_metric` uses the NVD's v3.1 score.
- `evaluator_impact` holds the NVD's note on how to weigh the impact of the memory leak; few CVEs have one.
- `enrichment.cisa_kev` shows it entered the CISA KEV catalog on 2022-05-04, eight years after publication.
- `enrichment.cpe[].affected_versions` lists the OpenSSL releases inside each affected range (1.0.1 to 1.0.1f).

When evaluating the impact of this vulnerability to your organization, take into account the nature of the data that is being protected and act according to your organization’s risk acceptance. While CVE-2014-0160 does not allow unrestricted access to memory on the targeted host, a successful exploit does leak information from memory locations which have the potential to contain particularly sensitive information, e.g., cryptographic keys and passwords.  Theft of this information could enable other attacks on the information system, the impact of which would depend on the sensitivity of the data and functions of that system.",
