Overview
CVE-2025-58309 is a permission control vulnerability identified in the startup recovery module of a specific system. Disclosed on 2025-11-28, this vulnerability carries a CVSS score of 6.8, indicating a medium severity. Successful exploitation could lead to a compromise of system availability and confidentiality.
Technical Details
The vulnerability stems from inadequate permission control within the startup recovery module. Specifically, an attacker, possibly with local access or through exploiting another vulnerability, can manipulate the recovery process to gain unauthorized access or modify critical system files. The exact method of exploitation will vary depending on the system affected, but it typically involves bypassing intended security checks during the startup or recovery phase. Further investigation is needed on the vendor’s side for specifics.
CVSS Analysis
- CVSS Score: 6.8 (Medium)
- The score reflects the potential for an attacker to impact both the availability and confidentiality of the system. The medium severity indicates that while the exploit may not be trivial, it’s achievable by attackers with moderate skill and resources.
Possible Impact
Successful exploitation of CVE-2025-58309 can have significant consequences:
- Loss of Confidentiality: Sensitive data stored on the system could be exposed to unauthorized individuals.
- Denial of Service (DoS): The system could be rendered unusable due to corruption of system files or manipulation of the recovery process.
- Privilege Escalation: An attacker might gain elevated privileges, allowing them to perform administrative tasks or install malicious software.
Mitigation or Patch Steps
To mitigate the risk posed by CVE-2025-58309, the following steps are recommended:
- Apply the official patch: Immediately apply the security patch released by the vendor (in this case, Huawei).
- Monitor system logs: Regularly monitor system logs for suspicious activity that might indicate an attempted exploitation.
- Restrict access: Implement strict access control policies to limit who can interact with the startup recovery module.
- Principle of Least Privilege: Ensure that all users and processes have only the minimum necessary privileges to perform their tasks.
