A vulnerability was determined in SeaCMS up to 13.6. Affected is the function parseIf of the file search.php of the component Template Engine. This manipulation of the argument searchtype causes code injection. It is possible to initiate the attack remotely. The exploit has been publicly disclosed and may be utilized.
AnalysisAI
Remote code injection in SeaCMS 13.6 and earlier allows unauthenticated network attackers to execute arbitrary code by passing malicious input through the searchtype parameter, which flows into the parseIf function of the template engine in search.php without adequate sanitization. A public proof-of-concept exploit has been disclosed on GitHub under the title 'cascade-template-rce,' materially lowering the attack threshold for any internet-exposed instance. …
