CVE-2019-0213

Root

Cause Apache Archiva versions 2.0.0 through 2.2.3 (and the unsupported 1.x series) contain a stored cross-site scripting (XSS) vulnerability in central configuration entries. Specifically, the logo URL field and similar UI configuration values do not properly sanitize user input, allowing an attacker to inject malicious JavaScript code that is stored on the server [1][4].

Attack

Vector Exploitation requires admin-level privileges to modify the configuration, or an attacker would need to have already compromised the communication channel between the browser and the Archiva server. This limits the attack surface to users with administrative roles or those capable of man-in-the-middle attacks [1][4]. The stored XSS then executes in the context of other administrators or users who view the affected configuration pages.

Impact

An attacker who successfully injects XSS can perform actions on behalf of other authenticated users, potentially leading to data theft, session hijacking, or further compromise of the Archiva server. The vulnerability is considered low severity due to the prerequisite of admin credentials, but it is still a valid security risk in multi-tenant or shared administrator scenarios [1][4].

Mitigation

Apache has released Archiva version 2.2.4, which fixes the stored XSS vulnerability. Users are strongly advised to upgrade to this version or later. No binary patches are provided for individual vulnerabilities; upgrading the entire application is the recommended remediation [3][4].
