CVE-2019-19025: 
Harbor vulnerability analysis and mitigation

Cloud Native Computing Foundation Harbor versions prior to 1.8.6 and 1.9.3 contained a critical Cross-Site Request Forgery (CSRF) vulnerability in the VMware Harbor Container Registry for Pivotal Platform. The vulnerability was discovered by Cure53 and disclosed on December 4, 2019. The issue affected the Harbor web interface, which lacked proper CSRF protection mechanisms (GitHub Advisory, VMware Security).

The vulnerability stems from the absence of CSRF protection mechanisms in the Harbor web interface. This security flaw has been assigned a CVSS v3 Base Score of 8.8 (High), with attack vector being Network-based, requiring no privileges but necessitating user interaction. The vulnerability allows attackers to execute actions on the platform through cross-site request forgery attacks (AttackerKB).

By exploiting this vulnerability, an attacker can execute any action on the platform in the context of the currently authenticated victim. This occurs when an authenticated user is lured onto a prepared third-party website, allowing the attacker to perform unauthorized actions with the victim's privileges (GitHub Advisory).

The vulnerability has been patched in Harbor versions 1.8.6 and 1.9.3. Users are strongly advised to upgrade to these patched versions immediately. There are no workarounds available for this vulnerability; the only solution is to update to the fixed versions (GitHub Advisory).
