CVE-2012-10058

Status: DeferredCritical (10)—

RabidHamster R4 v1.25 contains a stack-based buffer overflow vulnerability due to unsafe use of sprintf() when logging malformed HTTP requests. A remote attacker can exploit this flaw by sending a specially crafted URI, resulting in arbitrary code execution under the context of the web server process.

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 AV:N/PR:N/UI:N indica explotación remota sin privilegios ni interacción (T1190). Buffer overflow en sprintf() permite ejecución arbitraria de código (T1059).

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