CVE-2017-6564

Status: ModifiedMedium (6.5)—

On Franklin Fueling Systems TS-550 evo 2.3.0.7332 devices, the Guest user, which contains the lowest privileges, can post to the idSourceFileName parameter found within the /download directory. This ability allows for an attacker to download sensitive system files from the host machine such as databases which contain information that can aid in further attacks.

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).
