CVE-2024-26265 — Liferay Liferay Portal security vulnerability

Medium CVSS 6.5

The Image Uploader module in Liferay Portal 7.2.0 through 7.4.3.15, and older unsupported versions, and Liferay DXP 7.4 before update 16, 7.3 before update 4, 7.2 before fix pack 19, and older unsupported versions relies on a request parameter to limit the size of files that can be uploaded, which allows remote authenticated users to upload arbitrarily large files to the system's temp folder by modifying the `maxFileSize` parameter.

Matched remediation archetype

Resource exhaustion and denial of service

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Identify attacker-influenced work factors including input size, nesting, compression, fan-out, regex cost, allocation, recursion, retries, and connection lifetime.
  • Map per-request and shared CPU, memory, disk, descriptor, thread, queue, and downstream-service limits.
  • Determine whether authentication, tenancy, quotas, and rate controls apply before expensive processing begins.

Remediate safely

  • Bound input size, nesting, expansion, work, concurrency, queue depth, retries, and execution time before resource-intensive processing.
  • Release resources on every success, error, cancellation, and timeout path and use backpressure instead of unbounded buffering.
  • Update affected components and add small deterministic tests that assert resource ceilings rather than exhausting a host.
