CVE-2021-32305 Scanner

WebSVN is a web-based version control repository browser for SVN (Subversion), which helps web developers manage code repositories and collaborate on software development projects. The product offers a user-friendly interface that allows developers to browse, view, and download code from a remote SVN repository, along with other features such as diff, annotate, and revision history.

CVE-2021-32305 is a critical vulnerability that was recently discovered in WebSVN before version 2.6.1. The vulnerability is caused by the lack of input sanitization in the search parameter, which can allow remote attackers to execute arbitrary commands on vulnerable systems. Attackers can exploit this vulnerability by sending specially crafted search queries that contain shell metacharacters, such as semicolons, pipes, or backticks, to inject and execute their own code.

If the CVE-2021-32305 vulnerability is successfully exploited, it can lead to severe consequences for the affected system and its users. Attackers can gain full control of the system, steal confidential data, install malware or ransomware, or launch distributed denial-of-service (DDoS) attacks. Moreover, the compromised system can also be used as a pivot point to launch additional attacks on other systems within the same network.
