CVE-2019-11048· NVD / CVE Program· CNA php

Temporary files are not cleaned after OOM when parsing HTTP request data

Noroxi assessment

Priority: Monitor (action score 23/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 6.2% (FIRST EPSS); higher than 93.4% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: apcu-panel (AlmaLinux:8) 5.1.17-1.module_el8.3.0+2009+b272fdef; libzip (AlmaLinux:8) 1.5.2-1.module_el8.5.0+152+112d3b8c, 1.5.2-1.module_el8.3.0+2009+b272fdef, 1.5.2-1.module_el8.4.0+2229+b272fdef; libzip-devel (AlmaLinux:8) 1.5.2-1.module_el8.3.0+2009+b272fdef, 1.5.2-1.module_el8.4.0+2229+b272fdef, 1.5.2-1.module_el8.5.0+152+112d3b8c.

Low priority for now. Upgrade to apcu-panel (AlmaLinux:8) 5.1.17-1.module_el8.3.0+2009+b272fdef; libzip (AlmaLinux:8) 1.5.2-1.module_el8.5.0+152+112d3b8c, 1.5.2-1.module_el8.3.0+2009+b272fdef, 1.5.2-1.module_el8.4.0+2229+b272fdef; libzip-devel (AlmaLinux:8) 1.5.2-1.module_el8.3.0+2009+b272fdef, 1.5.2-1.module_el8.4.0+2229+b272fdef, 1.5.2-1.module_el8.5.0+152+112d3b8c or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

In PHP versions 7.2.x below 7.2.31, 7.3.x below 7.3.18 and 7.4.x below 7.4.6, when HTTP file uploads are allowed, supplying overly long filenames or field names could lead PHP engine to try to allocate oversized memory storage, hit the memory limit and stop processing the request, without cleaning up temporary files created by upload request. This potentially could lead to accumulation of uncleaned temporary files exhausting the disk space on the target server.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
