Search Vulnerabilities

Versions 00.07.00 through 00.07.03 of Teltonika’s RUT router firmware contain an operating system (OS) command injection vulnerability in a Lua service. An attacker could exploit a parameter in the vulnerable function that calls a user-provided package name by instead providing a package with a malicious name that contains an OS command injection payload.

Version 00.07.03.4 and prior of Teltonika’s RUT router firmware contain a packet dump utility that contains proper validation for filter parameters. However, variables for validation checks are stored in an external configuration file. An authenticated attacker could use an exposed UCI configuration utility to change these variables and enable malicious parameters in the dump utility, which could result in arbitrary code execution.

Relative Path Traversal in Teltonika firmware TRB2_R_00.02.04.3 allows a remote, authenticated attacker to read the contents of arbitrary files on disk.

Relative Path Traversal in Teltonika firmware TRB2_R_00.02.04.3 allows a remote, authenticated attacker to delete arbitrary files on disk via the admin/system/admin/certificates/delete action.

Insufficient output sanitization in Teltonika firmware TRB2_R_00.02.04.3 allows an unauthenticated attacker to conduct reflected cross-site scripting via a crafted ‘action’ or ‘pkg_name’ parameter.

Relative Path Traversal in Teltonika firmware TRB2_R_00.02.04.3 allows a remote, authenticated attacker to delete arbitrary files on disk via the admin/services/packages/remove action.

Server-Side Request Forgery in Teltonika firmware TRB2_R_00.02.04.3 allows a low privileged user to cause the application to perform HTTP GET requests to arbitrary URLs.

Cross-site request forgery in Teltonika firmware TRB2_R_00.02.04.3 allows a remote attacker to perform sensitive application actions by tricking legitimate users into clicking a crafted link.

Improper Input Validation in Teltonika firmware TRB2_R_00.02.04.01 allows a remote, authenticated attacker to gain root privileges by uploading a malicious package file.

Cross-site request forgery in Teltonika firmware TRB2_R_00.02.04.01 allows a remote attacker to perform sensitive application actions by tricking legitimate users into clicking a crafted link.

Improper Input Validation in Teltonika firmware TRB2_R_00.02.04.01 allows a remote, authenticated attacker to gain root privileges by uploading a malicious backup archive.

Improper Access Control in Teltonika firmware TRB2_R_00.02.04.01 allows a low privileged user to perform unauthorized write operations.

Insufficient output sanitization in Teltonika firmware TRB2_R_00.02.02 allows a remote, authenticated attacker to conduct persistent cross-site scripting (XSS) attacks by injecting malicious client-side code into the 'URL/ Host / Connection' form in the 'DATA TO SERVER' configuration section.
