CVE-2018-25338

Status: DeferredHigh (8.8)—

Zechat 1.5 contains a SQL injection vulnerability in the hashtag parameter that allows unauthenticated attackers to extract database information using union-based techniques. Attackers can exploit the hashtag parameter with union-based payloads to retrieve table and column names.

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.

SQL injection en parámetro accesible sin autenticación (AV:N, PR:N) permite lectura de datos mediante UNION-based queries (T1005). Potencial de manipulación si el atacante escribe datos (T1565.001) con baja confianza por falta de mención explícita.

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