Severity

high7.1

CVSS measures technical severity, not the likelihood of an attack.

Known exploitation

Not listed in the checked CISA KEV catalog

Absence from CISA KEV does not rule out attacks.

Public exploit

Not established by this record

Missing evidence does not mean no public exploit exists.

Remediation

Source guidance available

Review the recorded instructions. Guidance may be a workaround rather than a fixed version.

What this means

HTTP::Body versions before 1.23_01 for Perl may leave temporary files on disk after incomplete multipart uploads, potentially allowing a remote attacker to fill the temporary directory. The weakness is due to incomplete cleanup. The impact is uncertain.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

Public exploit evidence

Original source description

Read the full publisher description

HTTP::Body versions before 1.23_01 for Perl leave the temporary file of an incomplete multipart upload on disk.

The multipart parser creates a temporary file as soon as a file part starts, but adds it to the upload list only when the part completes. Uploads are only ever deleted from that list, by the cleanup option or by the caller, so a body that ends inside a file part leaves its temporary file where nothing can find it.

A remote attacker can fill the temporary directory by repeating such requests, leaving one file behind for each.
