CyberRota Analysis

AI-Generated

Dendrite versions up to 0.13.8 are vulnerable to a server-side request forgery (SSRF) that enables unauthenticated attackers to initiate outbound TLS connections to arbitrary hosts by manipulating the serverName parameter in the media download endpoint. This vulnerability can lead to information disclosure through error messages, allowing attackers to conduct blind port scanning and map internal network structures. Organizations using affected Dendrite versions should prioritize remediation to mitigate potential exposure of their internal network.

Original NVD Description

Dendrite through 0.13.8 contains a server-side request forgery vulnerability that allows unauthenticated attackers to cause the server to open outbound TLS connections to arbitrary hosts and ports by supplying an unvalidated serverName parameter to the legacy media download endpoint. Attackers can exploit distinguishable error response classes and leaked internal IP addresses in error messages to perform blind port scanning and enumerate internal network topology.
