CVE-2024-0799 is a critical-severity Improper Authentication (CWE-287) vulnerability in Arcserve Udp. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 2.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
An authentication bypass vulnerability exists in Arcserve Unified Data Protection versions 9.2 and 8.1, specifically within the doLogin function of the EdgeLoginServiceImpl class inside edge-app-base-webui.jar that handles wizardLogin requests. The flaw is tracked as CVE-2024-0799 with a CVSS 3.1 score of 9.8 and is associated with CWE-287.
Remote attackers can exploit the issue over the network without authentication or user interaction to obtain full control over confidentiality, integrity, and availability of the affected data protection system. The attack vector requires no privileges and targets the exposed web interface component directly.
Public research from Tenable at the referenced TRA-2024-07 advisory provides further technical details on the flaw. The associated EPSS score rose from lower values after disclosure to a peak of 0.5151 on 2025-12-11 before receding to the current 0.3788, indicating a period of increased exploitation interest.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Detects unauthorized successful logons resulting from improper authentication implementations.
Documented procedures ensure personnel are trained on authentication mechanisms, tangibly lowering the risk of improper authentication being exploited.
Security awareness training instructs users on secure authentication practices and avoiding credential compromise.
Training on authentication mechanisms and best practices decreases the occurrence of improper authentication.
Non-repudiation requires strong authentication mechanisms to irrefutably attribute performed actions to specific individuals or processes.
Session content review can reveal authentication bypasses or failures in session establishment.
Review of authentication-related audit records can detect improper authentication mechanisms or bypasses.
Assessments check authentication mechanisms for correct implementation and effectiveness, reducing successful authentication bypass attempts.
