Technical Analysis

Adobe Commerce, which is based on the Magento PHP suite, is a popular framework for commerce websites. CVE-2024-34102 is a critical unauthenticated XML injection vulnerability, initially reported by Sergey Temnikov, that targets Commerce. Unsafe deserialization of data is performed with tainted JSON string data, which results in an attacker-controlled SimpleXMLElement class that will resolve external entities.

An attacker with unauthenticated access to Adobe Commerce can send a crafted JSON string containing an XML object that embeds DTDs to read local files, including the env.php that contains the JWT secret. With this information, an attacker can forge their own privileged session token and authenticate to Adobe Commerce as an administrator. Sergey also reported that the vulnerability can be chained with the recent iconv bug in the glibc for RCE via PHP filters.

A Metasploit gather module for CVE-2024-34102 was contributed to the framework by @heyder. Anyone running Adobe Commerce or Magento that has not updated should do so urgently, since the vulnerability can be exploited without authentication for critical impact. Adobe has provided an official fix for the vulnerability that can be applied over previous emergency hotfixes.
