Aztech » Adsl Dsl5018en (1t1r) Firmware : Security Vulnerabilities, CVEs, (Gain Privilege)

Aztech ADSL DSL5018EN (1T1R), DSL705E, and DSL705EU devices improperly manage sessions, which allows remote attackers to bypass authentication in opportunistic circumstances and execute arbitrary commands with administrator privileges by leveraging an existing web portal login.

cgi-bin/AZ_Retrain.cgi in Aztech ADSL DSL5018EN (1T1R), DSL705E, and DSL705EU devices does not check for authentication, which allows remote attackers to cause a denial of service (WAN connectivity reset) via a direct request.
