CVE-2023-2650 is a Denial of Service vulnerability in OpenSSL versions 3.0 and newer, where processing specially crafted ASN.1 object identifiers with very large sub-identifiers can lead to significant delays. This affects applications directly using OBJ_obj2txt() or OpenSSL subsystems like OCSP, PKCS7/SMIME, CMS, CMP/CRMF, or TS without message size limits. Rated as MEDIUM severity (CVSS 6.5), the vulnerability has a network attack vector and low attack complexity, potentially causing a complete denial of service (A:H). While user interaction is required (UI:R), the impact on confidentiality and integrity is none. There is no evidence of active exploitation, and no public exploit code is available in Metasploit, Nuclei, or ExploitDB. However, the CVE has garnered some community discussion and media coverage, indicating awareness of the issue.
