T10 Firmware
Monthly
A vulnerability has been found in TOTOLINK T10 4.1.8cu.5241_B20210927. Rated medium severity (CVSS 6.9), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Privilege escalation and unauthorized file access affects TOTOLINK A7100RU (V7.4), A950RG (V5.9), and T10 (V5.9) routers because their bundled vsftpd FTP server ships with the chroot_local_user option enabled in vsftpd.conf, an insecure default that can let a local FTP user reach system files and escalate on the device. On these consumer routers the FTP daemon runs with high privilege and weak isolation, so a foothold on the FTP service can be used to read sensitive files, gain elevated access, and pivot into the internal network. There is no CISA KEV listing and no public exploit identified at time of analysis; the only reference is a researcher gist, and EPSS is low at 0.34% (26th percentile).
Hard-coded password in TOTOLINK T10 firmware 4.1.8cu.5207 allows local network attackers with high privileges to access the /etc/shadow.sample file. The vulnerability is publicly exploited but has a low EPSS score (0.05%) and high attack complexity, limiting real-world risk.
Critical buffer overflow vulnerability in TOTOLINK T10 firmware version 4.1.8cu.5207 affecting the HTTP POST request handler. An authenticated attacker can remotely exploit the setWizardCfg function via the ssid5g parameter to achieve buffer overflow, resulting in complete system compromise including confidentiality, integrity, and availability breaches. Public exploit code has been disclosed and the vulnerability meets criteria for active exploitation risk.
Critical buffer overflow vulnerability in TOTOLINK T10 firmware version 4.1.8cu.5207 affecting the setWiFiScheduleCfg function in the HTTP POST request handler. An authenticated remote attacker can exploit this vulnerability by manipulating the 'desc' parameter to achieve buffer overflow, resulting in complete compromise of confidentiality, integrity, and availability. A public exploit has been disclosed and the vulnerability is likely actively exploited given its critical CVSS score of 8.8 and low attack complexity.
Critical buffer overflow vulnerability in TOTOLINK T10 firmware version 4.1.8cu.5207 affecting the WiFi repeater configuration function. An authenticated remote attacker can exploit this vulnerability by sending a malicious POST request with an oversized Password parameter to /cgi-bin/cstecgi.cgi, achieving complete compromise of the device including arbitrary code execution. Public disclosure and proof-of-concept code availability significantly elevate real-world risk despite requiring authenticated access.
