Public exploitAvailablePublished on Exploit-DB

The xmlrpc extension in PHP 5.3.1 does not properly handle a missing methodName element in the first argument to the xmlrpc_decode_request function, which allows context-dependent attackers to cause a denial of service (NULL pointer dereference and application crash) and possibly have unspecified other impact via a crafted argument.

CVSS

Base score: 5
Version: 2.0
Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 12 %
Percentile among all scored CVEs: 96
Score date: 10/21/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
