Comprehensive Technical Analysis of CVE-2025-10644

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-10644 CISA Vulnerability Name: CVE-2025-10644 CVSS Score: 9.4

The vulnerability in question is an Incorrect Permission Assignment Authentication Bypass in Wondershare Repairit, specifically related to the permissions granted to an SAS (Shared Access Signature) token. This flaw allows remote attackers to bypass authentication mechanisms, potentially leading to unauthorized access and arbitrary code execution on customers' endpoints.

Severity Evaluation:

• CVSS Score: 9.4 (Critical)
• Impact: High
• Exploitability: High

The high CVSS score indicates a critical vulnerability that can be easily exploited by attackers without requiring authentication. The potential for arbitrary code execution and supply-chain attacks significantly elevates the risk.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Remote Exploitation: Attackers can exploit this vulnerability remotely, making it a high-risk vector.
2. Supply-Chain Attack: The ability to execute arbitrary code on customers' endpoints suggests that attackers could inject malicious code into the software supply chain.

Exploitation Methods:

1. SAS Token Manipulation: Attackers can manipulate the SAS token to gain unauthorized access to the system.
2. Authentication Bypass: By leveraging the incorrect permission assignment, attackers can bypass authentication mechanisms.
3. Code Execution: Once access is gained, attackers can execute arbitrary code, leading to potential data breaches, system compromise, and further malicious activities.
