CVE-2026-49201

Status: AnalyzedCritical (10)—

The upload.cgi binary, responsible for processing device backups, contains a hardcoded AES encryption key. This allows an attacker to decrypt, modify, and re-encrypt system backups, facilitating persistent backdoor injection.

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 de red sin autenticación (AV:N/PR:N/UI:N) indica T1190. CWE-798 (credenciales hardcodeadas) permite acceso persistente. Impactos: credenciales descubiertas (T1078.001), modificación de backups (T1565.001), inyección de puerta trasera persistente (T1547.001).

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