CVE-2005-4449

Status: ModifiedMedium (4)—💥 Exploit

verify.php in FlatNuke 2.5.6 allows remote authenticated administrators to modify arbitrary PHP files by setting the file parameter to an arbitrary file and injecting the code into the body parameter. NOTE: if a FlatNuke administrator is normally assumed to be able to modify arbitrary content, then this issue does not cross privilege boundaries and would not be a vulnerability.

CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:S/C:N/I:P/A:N
Base score: 4

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 4.59%
Percentile among all scored CVEs: 91
Score date: 10/7/2026

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.
