Comprehensive Technical Analysis of CVE-2024-22988

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-22988 CVSS Score: 9.8

The vulnerability in ZKteco ZKBio WDMS before version 9.0.2 Build 20250526 allows an attacker to download a database backup via the /files/backup/ component due to a predictable timestamp in the filename. This vulnerability is classified as critical with a CVSS score of 9.8, indicating a high risk of exploitation with severe potential consequences.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: An attacker can exploit this vulnerability without needing authentication, making it highly accessible.
• Predictable Filenames: The use of predictable timestamps in the filenames of database backups allows attackers to easily guess the correct filename.

Exploitation Methods:

• Direct URL Access: An attacker can directly access the backup files by constructing the URL with the predictable timestamp.
• Automated Scripts: Attackers can use automated scripts to iterate through possible timestamps and download the database backups.

3. Affected Systems and Software Versions
