AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Authentication bypass in Netgear WNR1000v3 firmware <1.0.2.60 allows attackers to retrieve device configuration via URLs containing '.jpg', bypassing authentication.
Vulnerability
The web server on Netgear WNR1000v3 with firmware versions before 1.0.2.60 skips authentication checks for URLs containing the substring .jpg. This allows an unauthenticated attacker to access sensitive pages, such as the device configuration file at /NETGEAR_fwpt.cfg?.jpg, bypassing the authentication mechanism [1].
Exploitation
An attacker can exploit this by simply sending a request to the vulnerable URL without any prior authentication. The retrieved configuration file is encrypted using a weak encryption scheme (a variation of the key NtgrBak) that can be reversed with a publicly available Python script [1].
Impact
Successful exploitation allows an attacker to obtain the configuration file, which contains the clear-text admin password after decryption. This grants full administrative control over the router, leading to compromise of confidentiality and integrity of the network [1].
Mitigation
The vendor released firmware version 1.0.2.60 to address this vulnerability. Users should update to this version or later. No workarounds are mentioned in the reference [1].
