Information disclosure via unchecked listener URL
Published Feb 15, 2022 · Updated Aug 3, 2024
Authentication bypass in Cobalt Strike 4.5 and earlier allows remote attackers to obtain information via crafted HTTP(S) listener URLs. The HTTP(S) listener fails to verify that a request URL begins with "/", allowing attacker-specified paths to return relevant listener data. Exploitation requires network access to an exposed listener and is bounded to information disclosure; the record does not document modification or service interruption.
