CVE-2024-45031: Apache Syncope: Stored XSS in Console and Enduser

Severity: medium (CVSS 6.1 v3.1)
Exploited in the wild: not listed in CISA KEV
EPSS: 0.7% probability of exploitation in the next 30 days
Public exploit or detection template: none known
Published: 2024-10-24 · updated 2026-06-17
Weakness: CWE-79

Description

When editing objects in the Syncope Console, incomplete HTML tags could be used to bypass HTML sanitization. This made it possible to inject stored XSS payloads which would trigger for other users during ordinary usage of the application. XSS payloads could also be injected in Syncope Enduser when editing “Personal Information” or “User Requests”: such payloads would trigger for administrators in Syncope Console, thus enabling session hijacking. Users are recommended to upgrade to version 3.0.9, which fixes this issue.

Affected products

Apache Software Foundation Apache Syncope: from 2.1.0 before 3.0.9 — fixed in 3.0.9

How to fix

Upgrade to a fixed version: Apache Software Foundation Apache Syncope 3.0.9. Check the vendor advisory for mitigations.
