Technical Details of CVE-2023-52075

The technical details of CVE-2023-52075 include the vulnerability description, affected systems and versions, and the exploitation mechanism.

Vulnerability Description

The ReVanced API, up to and including commit 71f81f7f20cd26fd707335bca9838fa3e7df20d2, lacks error caching, causing the rate limit to be triggered and increasing server load. This results in a denial of service for all API users. It is advised to implement proper error caching to mitigate this issue.

Affected Systems and Versions

The affected system is the ReVanced API, specifically the 'revanced-api' product. Versions up to and including commit 71f81f7f20cd26fd707335bca9838fa3e7df20d2 are vulnerable to the denial-of-service condition.

Exploitation Mechanism

The exploitation of this vulnerability involves sending requests to the ReVanced API in a way that triggers the rate limit due to lack of error caching, causing a denial of service for legitimate users.

Mitigation and Prevention

This section will provide guidance on the immediate steps to take, long-term security practices, and the importance of patching and updates.

Immediate Steps to Take

To mitigate the CVE-2023-52075 vulnerability, it is crucial to implement proper error caching in the ReVanced API codebase. By addressing this issue, the risk of a denial-of-service attack can be significantly reduced.

Long-Term Security Practices
