A vulnerability was found in Undertow where the ProxyProtocolReadListener reuses the same StringBuilder instance across multiple requests. This issue occurs when the parseProxyProtocolV1 method processes multiple requests on the same HTTP connection. As a result, different requests may share the same StringBuilder instance, potentially leading to information leakage between requests or responses. In some cases, a value from a previous request or response may be erroneously reused, which could lead to unintended data exposure. This issue primarily results in errors and connection termination but creates a risk of data leakage in multi-request environments.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A vulnerability was found in Undertow where the ProxyProtocolReadListener reuses the same StringBuilder     instance across multiple requests. This issue occurs when the parseProxyProtocolV1 method processes     multiple requests on the same HTTP connection. As a result, different requests may share the same     StringBuilder instance, potentially leading to information leakage between requests or responses. In some     cases, a value from a previous request or response may be erroneously reused, which could lead to     unintended data exposure. This issue primarily results in errors and connection termination but creates a     risk of data leakage in multi-request environments. (CVE-2024-7885)

Note that Nessus relies on the presence of the package as reported by the vendor.
