Описание
Impact: multer versions 2.0.0-alpha.1 through 2.1.1 and 3.0.0-alpha.1 are vulnerable to a Denial of Service when using diskStorage. Aborted or malformed multipart uploads leave orphaned partial files on disk because the Readable.pipe() call does not propagate the stream destroy signal to
the underlying fs.WriteStream. An attacker can exhaust disk space by triggering many aborted uploads, with no application bug required.
Patches: Users should upgrade to multer 2.2.0 (2.x line) or 3.0.0-alpha.2 (3.x prerelease). Both versions track in-flight write streams and clean them up on the abort path.
Workarounds: None.
A flaw was found in multer. This vulnerability allows a remote attacker to trigger a Denial of Service (DoS) by initiating and then aborting or sending malformed multipart uploads. This action leaves orphaned partial files on the disk, which can lead to the exhaustion of available disk space without requiring any specific application bug.
Отчет
This is an Important denial of service vulnerability in multer when configured to use diskStorage. An attacker can exploit this flaw by initiating and then aborting or sending malformed multipart uploads, leading to the accumulation of orphaned partial files and eventual disk space exhaustion on affected Red Hat products that utilize multer for file handling.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
