CVE-2021-47795

Status: DeferredHigh (8.7)—

GeoVision GeoWebServer 5.3.3 contains multiple vulnerabilities including local file inclusion, cross-site scripting, and remote code execution through improper input sanitization. Attackers can exploit the WebStrings.srf endpoint by manipulating path traversal and injection parameters to access system files and execute malicious scripts.

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.

AV:N/PR:N acceso remoto sin privilegios apunta a T1190. CWE-22 (path traversal) y LFI permiten lectura de archivos (T1005); RCE mencionado en WebStrings.srf sugiere T1059 como impacto secundario.

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