• Public exploit or detection template: none known

Description

SAP Integration Suite does not sufficiently validate XML documents accepted from untrusted sources in certain internal components. An attacker with low privileges could submit specially crafted XML payloads containing malicious external entity declarations. Successful exploitation could allow the attacker to read sensitive file contents from the server and expose them through monitoring or logging output, resulting in a high impact on confidentiality. It could also lead to resource exhaustion, causing a low impact on availability. There is no impact on integrity.
