CVE-2020-19285

Vulnerability

A stored cross-site scripting (XSS) vulnerability exists in the /group/apply component of Jeesns version 1.4.2. The Name text field fails to sanitize user input, enabling an attacker to inject arbitrary web scripts or HTML. This flaw is documented in the Seebug vulnerability database [1].

Exploitation

An attacker must have access to the group application functionality. By submitting a crafted payload in the Name field, the malicious script is stored on the server. When an administrator or other user views the group application list or details, the script executes in their browser.

Impact

Successful exploitation allows arbitrary JavaScript execution in the context of the victim's browser. This can lead to session hijacking, defacement, or theft of sensitive data. The impact is confined to users who view the affected page.

Mitigation

No official patch has been released for Jeesns 1.4.2 as of the publication date (2021-09-09). Users should upgrade to a newer version if available, or implement input validation and output encoding for the Name field. The vulnerability is listed on Seebug [1] but no fix is provided.
