An improper restriction of external entities (XXE) vulnerability in dompdf/dompdf's SVG parser allows for Server-Side Request Forgery (SSRF) and deserialization attacks. This issue affects all versions prior to 2.0.0. The vulnerability can be exploited even if the isRemoteEnabled option is set to false. It allows attackers to perform SSRF, disclose internal image files, and cause PHAR deserialization attacks.
#TTP

a globally-accessible knowledge base of adversary tactics and techniques based on real-world observations.

The Technique Inference Engine (TIE) suggests techniques an adversary is likely to have used based on a set of observed techniques. Cyber defenders can use this data to prioritize specific techniques for threat hunting, and incident responders can use this information to highlight important lateral movement and persistence behaviors that are essential to threat eviction and recovery.
