Improper Input Validation vulnerability (CVE-2021-41585) was identified in Apache Traffic Server's socket connection handling mechanism. The vulnerability affects Apache Traffic Server versions from 5.0.0 to 9.1.0, where an attacker could exploit this issue to prevent the server from accepting new connections (NVD, CVE).
