The National Vulnerability Database records this issue with a CVSS score of 9.9. This rating places the flaw in the critical severity category. The vulnerability stems from weaknesses in how the software handles authorization and input validation. According to the NVD record, the issue is classified under CWE-264, which relates to permission issues.
Technical Details of the Vulnerability
An authenticated attacker can craft a malicious request to exploit this vulnerability. This request bypasses additional authorization checks that are meant to protect the system. The flaw also allows the attacker to skip input validation procedures. As a result, the attacker can execute malicious code on the target system.
The execution of this code grants the attacker elevated privileges. This means the attacker gains higher-level access than their original credentials allow. The NVD description states that an attacker could exploit this to obtain elevated privileges. This level of access can compromise the integrity of the entire system.
