CVE-2024-52596 [HIGH] SimpleSAMLphp vulnerabilities
Title: SimpleSAMLphp vulnerabilities
Summary: Several security issues were fixed in SimpleSAMLphp.
It was discovered that SimpleSAMLphp incorrectly validated cryptographic
signatures in XML messages. An authenticated attacker could possibly use
this issue to impersonate users or gain elevated privileges. This issue
only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2019-3465)
It was discovered that SimpleSAMLphp incorrectly handled external entities
when parsing untrusted XML documents. A remote attacker could possibly use
this issue to obtain sensitive information. This issue did not affect
Ubuntu 24.04 LTS. (CVE-2024-52596)
It was discovered that SimpleSAMLphp incorrectly verified signatures in
SAML messages using the HTTP-Redirect binding. A remote attacker could
possibly use
