5.0
CVSS v3.1
Official Description
chatbox.php in e107 0.554 and 0.603 allows remote attackers to cause a denial of service (pages fail to load) via HTML in the Name field, which prevents the main.php form from being loaded.
Technical Analysis
CVE-2003-1191 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A proof-of-concept (PoC) exploit exists for CVE-2003-1191. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
