CVE-2014-3931

Status: AnalyzedCritical (9.8)⚠ Active exploitation

fastping.c in MRLG (aka Multi-Router Looking Glass) before 5.5.0 allows remote attackers to cause an arbitrary memory write and memory corruption.

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).

CISA KEV — actively exploited

🎯 ATT&CK techniques

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

Vector AV:N/PR:N/UI:N sin autenticación permite explotación remota de aplicación web (T1190). Buffer overflow (CWE-119) en fastping.c causa escritura arbitraria de memoria, permitiendo ejecución de código (T1059) y potencial DoS (T1499.004). Confirmado por KEV con explotación activa.

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