CVE-2009-3702

Status: ModifiedHigh (7.5)—💥 Exploit

Multiple absolute path traversal vulnerabilities in PHP-Calendar 1.1 allow remote attackers to include and execute arbitrary local files via a full pathname in the configfile parameter to (1) update08.php or (2) update10.php. NOTE: in some environments, this can be leveraged for remote file inclusion by using a UNC share pathname or an ftp, ftps, or ssh2.sftp URL.

CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
Base score: 7.5

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 2.45%
Percentile among all scored CVEs: 84
Score date: 10/8/2026

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.
