Deeper analysis
CVE-2024-38503 is a cross-site scripting vulnerability (CWE-79) that affects Apache Syncope. When editing a user, group, or other object in the Syncope Console, or when editing personal information or user requests in the Syncope Enduser interface, arbitrary HTML tags can be supplied in text fields.
An authenticated user with low privileges can supply the tags during normal editing operations, resulting in script execution that affects other users viewing the edited content and yields limited impacts on confidentiality and integrity as reflected in the CVSS 5.4 score.
The Apache Syncope project advisory states that users should upgrade to version 3.0.8, which contains the fix; the same guidance appears in the coordinated oss-security disclosure. The associated EPSS score has remained flat at 0.0596 with no material increase after disclosure.
