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

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.

Severity

Moderate

Affects

  • 3.0 through 3.0.8
  • 2.1 through 2.1.14

Solution

  • Users are recommended to upgrade to version 3.0.9, which fixes this issue.

Fixed in

  • Release 3.0.9

CVE-2024-38503: HTML tags can be injected into Console or Enduser text fields

When editing a user, group or any object in the Syncope Console, HTML tags could be added to any text field and could lead to potential exploits. The same vulnerability was found in the Syncope Enduser, when editing “Personal Information” or “User Requests”.

Severity

Moderate

Affects

  • 3.0 through 3.0.7
  • 2.1 through 2.1.14

Solution

  • Users are recommended to upgrade to version 3.0.8, which fixes this issue.

CVE-2020-1961: Server-Side Template Injection on mail templates

Vulnerability to Server-Side Template Injection on Mail templates enabling attackers to inject arbitrary JEXL expressions, leading to Remote Code Execution (RCE) was discovered.

Severity

Important

Affects

  • 2.0.X releases prior to 2.0.15
  • 2.1.X releases prior to 2.1.6

Solution

  • 2.0.X users should upgrade to 2.0.15

CVE-2020-1959: Multiple Remote Code Execution Vulnerabilities

A Server-Side Template Injection was identified in Syncope enabling attackers to inject arbitrary Java EL expressions, leading to an unauthenticated Remote Code Execution (RCE) vulnerability. Apache Syncope uses Java Bean Validation (JSR 380) custom constraint validators. When building custom constraint violation error messages, they support different types of interpolation, including Java EL expressions. Therefore, if an attacker can inject arbitrary data in the error message template being passed, they will be able to run arbitrary Java code.

Severity

Important

Affects

  • 2.1.X releases prior to 2.1.6

Solution

  • 2.1.X users should upgrade to 2.1.6

Fixed in

  • Release 2.1.6

Read the full CVE advisory.

CVE-2019-17557: Enduser UI XSS

It was found that the EndUser UI login page reflects the successMessage parameters. By this mean, a user accessing the Enduser UI could execute javascript code from URL query string.

Severity

Medium

Affects

  • 2.0.X releases prior to 2.0.15
  • 2.1.X releases prior to 2.1.6

Solution

  • 2.0.X users should upgrade to 2.0.15
  • 2.1.X users should upgrade to 2.1.6

Fixed in

  • Release 2.0.15
  • Release 2.1.6
