A vulnerability was found in Tenda FH1202 1.2.0.14(408). This impacts the function fromP2pListFilter of the file /goform/P2pListFilter. The manipulation of the argument page results in stack-based buffer overflow. The attack can be executed remotely. The exploit has been made public and could be us…

An unauthenticated remote attacker can obtain valid session tokens because they are exposed in plaintext within the URL parameters of the wwwupdate.cgi endpoint in UBR.

A high-privileged remote attacker can fully compromise the device by abusing an update signature bypass vulnerability in the wwwupdate.cgi method in the web interface of UBR.

A low-privileged remote attacker can trigger a stack-based buffer overflow via a crafted HTTP POST request using the ubr-network method resulting in full device compromise.

Due to insufficient authorization enforcement, an unauthorized remote attacker can exploit the wwwupload.cgi endpoint to upload and apply arbitrary data. This includes, but is not limited to, contact images, HTTPS certificates, system backups for restoration, server peer configurations, and BACnet/…

Due to insufficient authorization enforcement, an unauthorized remote attacker can exploit the wwwupdate.cgi endpoint to upload and apply arbitrary updates.

A low‑privileged remote attacker can directly interact with the wwwdnload.cgi endpoint to download any resource available to administrators, including system backups and certificate request files.

An unauthenticated attacker can abuse the weak hash of the backup generated by the wwwdnload.cgi endpoint to gain unauthorized access to sensitive data, including password hashes and certificates.

A low‑privileged local attacker who gains access to the UBR service account (e.g., via SSH) can escalate privileges to obtain full system access. This is due to the service account being permitted to execute certain binaries (e.g., tcpdump and ip) with sudo.

An administrator may attempt to block all traffic by configuring a pass filter with an empty table. However, in UBR, an empty list does not enforce any restrictions and allows all network traffic to pass unfiltered.
