Summary
In Streambert versions 2.4.0 and prior, a Zip Slip vulnerability was identified in the subtitle extraction logic. The application does not sanitize archive entry filenames during extraction, allowing for path traversal attacks and writing arbitrary files to the host filesystem.
Risk Assessment
This vulnerability could lead to unauthorized access to the filesystem, posing a serious threat to the organization's data security. An attacker could exploit this flaw to place malicious software anywhere on the server.
Recommendation
It is recommended to update the Streambert application to version 2.5.0, where the issue has been fixed. Additionally, implementing monitoring and security mechanisms is advisable to minimize the risk associated with similar vulnerabilities in the future.
Original NVD description (English source)
Streambert is a cross-platform Electron Desktop App to stream and download any video media. In versions 2.4.0 and prior, a high-severity Zip Slip vulnerability was identified in Streambert's subtitle extraction logic. The application does not sanitize archive entry filenames during extraction, allowing a malicious archive to perform path traversal and write arbitrary files to the host filesystem. The subtitle extraction process downloads a ZIP archive and extracts its entries. The destination file path is constructed by concatenating the raw archive entry name (extracted.name) directly to the temporary directory path. If a malicious ZIP archive containing directory traversal sequences is processed, it escapes the temporary directory boundaries. The application then writes the extracted payload anywhere on the host filesystem subject to the application's current write permissions. This issue has been fixed in version 2.5.0.
