37
FAUCET Score

CVE-2015-7258 describes a critical vulnerability in ZTE ADSL ZXV10 W300 modems (firmware versions W300V2.1.0f_ER7_PE_O57 and W300V2.1.0h_ER7_PE_O57) that allows authenticated attackers to retrieve user passwords via Telnet. With a CVSS v3.0 score of 8.8 (High), this vulnerability presents a significant risk due to its network-based attack vector, low complexity, and high impact on confidentiality, integrity, and availability. While there is no evidence of active exploitation or Metasploit/Nuclei modules, an ExploitDB entry (EDB-38772) confirms the existence of exploit code, though community discussion and media coverage remain minimal.
