Elevated risk50th percentile - higher than 50% of all known CVEs
Summary
OpenBullet2 through version 0.3.2 contains a path traversal vulnerability in the wordlist endpoint that allows authenticated attackers to perform arbitrary file read, write, and delete operations by supplying unsanitized absolute paths to the upload handler and wordlist functions.
Risk Assessment
Attackers can exploit this vulnerability to achieve remote code execution by manipulating critical system files, leading to full system compromise since the application runs as root by default.
Recommendation
It is recommended to update OpenBullet2 to the latest version to mitigate this vulnerability and implement additional security measures, such as restricting application permissions.
Original NVD description (English source)
OpenBullet2 through version 0.3.2 contains a path traversal vulnerability in the wordlist endpoint that allows authenticated attackers to perform arbitrary file read, write, and delete operations by supplying unsanitized absolute paths to the upload handler and wordlist functions. Attackers can chain the file write and delete primitives to achieve remote code execution by manipulating critical system files such as /etc/passwd, with full system impact since the application runs as root by default.
