CVE-2026-76958: CWE-611: Improper Restriction of XML External Entity Reference in SAP_SE SAP Integration Suite
CVE-2026-76958 is a vulnerability in SAP Integration Suite where XML documents from untrusted sources are not sufficiently validated. This allows attackers with low privileges to submit crafted XML payloads containing malicious external entity declarations. Successful exploitation can lead to disclosure of sensitive server file contents and resource exhaustion, impacting confidentiality and availability respectively, but not integrity. The vulnerability has a high severity score of 8.5.
AI Analysis
Technical Summary
SAP Integration Suite does not properly restrict XML External Entity (XXE) references in certain internal components. An attacker with low privileges can submit specially crafted XML payloads containing malicious external entity declarations. Exploitation could allow reading sensitive files on the server exposed via monitoring or logging outputs, causing a high confidentiality impact. Additionally, it may cause resource exhaustion resulting in a low availability impact. There is no integrity impact. No patch or remediation information is currently available, and no known exploits are reported in the wild.
Potential Impact
Successful exploitation can disclose sensitive file contents on the server, leading to a high confidentiality impact. It can also cause resource exhaustion, resulting in a low impact on availability. There is no impact on data integrity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the SAP Integration Suite and monitor for suspicious XML payloads where possible.
