EUVDB-ID: #VU85287
Risk: Critical
CVSSv3.1: 9.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:H/RL:O/RC:C]
CVE-ID: CVE-2024-21887
CWE-ID:
CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Exploit availability: Yes
DescriptionThe vulnerability allows a remote user to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation. A remote authenticated administrator can pass specially crafted data to the application and execute arbitrary OS commands on the target system. However this vulnerability can be exploited by a non-authenticated attacker using authentication bypass vulnerability #VU85286 (CVE-2023-46805).
