CVE-2026-51623

Incorrect access control in the getDdnsStatus function of TOTOLINK T6 4.1.5cu.748B20211015 allows unauthenticated attackers to obtain DDNS runtime status and public IP information via sending a crafted POST request to /cgi-bin/cstecgi.cgi...

User Impersonation

Overview Affected versions of this package are vulnerable to User Impersonation via the readconfig.php process. An attacker can gain unauthorized access to sensitive system information by sending spoofed X-Forwarded-For or Client-IP HTTP headers to impersonate a trusted IP address. Remediation...

phpSysInfo has an IP allowlist (PSI_ALLOWED) bypass via spoofed X-Forwarded-For / Client-IP headers

Summary phpSysInfo's PSIALLOWED IP allowlist can be trivially bypassed by any unauthenticated remote attacker. The access-control check in readconfig.php derives the client IP from the attacker-controlled X-Forwarded-For and Client-IP HTTP headers before falling back to REMOTEADDR. An attacker ca...

CVE-2026-55584

phpSysInfo versions ≤ 3.4.5 contain an IP allowlist bypass in the PSI_ALLOWED check within read_config.php. The vulnerable code resolves the client IP from attacker-controlled X-Forwarded-For and Client-IP headers before falling back to REMOTE_ADDR, with no trusted-proxy concept. A remote unauthe...
