CVE-2025-65037

Comprehensive Technical Analysis of CVE-2025-65037

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-65037 Description: Improper control of generation of code ('code injection') in Azure Container Apps allows an unauthorized attacker to execute code over a network. CVSS Score: 10

The CVSS score of 10 indicates that this vulnerability is of critical severity. This high score is due to the potential for remote code execution (RCE), which can lead to complete system compromise. The vulnerability allows an attacker to inject malicious code into Azure Container Apps, enabling them to execute arbitrary commands on the affected systems.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: Given the nature of the vulnerability, attackers can exploit it over the network, making it accessible from remote locations.
• Malicious Inputs: Attackers can inject malicious code through various input vectors, such as API calls, configuration files, or user inputs processed by the Azure Container Apps.

Exploitation Methods:

• Code Injection: Attackers can inject malicious code into the application, which is then executed by the underlying system.
• Command Injection: By injecting commands, attackers can execute arbitrary system commands, leading to unauthorized access and control.
• Script Injection: Attackers can inject scripts that perform malicious actions, such as data exfiltration or system manipulation.

3. Affected Systems and Software Versions

Affected Systems:

• Azure Container Apps

Software Versions:

• Specific versions affected are not mentioned in the provided information. However, it is crucial to assume that all versions prior to the patch release are vulnerable.

4. Recommended Mitigation Strategies

Immediate Actions:

• Patch Management: Apply the latest security patches and updates provided by Microsoft for Azure Container Apps.
• Input Validation: Implement robust input validation and sanitization mechanisms to prevent malicious code injection.
