CVE-2024-8929· NVD / CVE Program· CNA php

Leak partial content of the heap through heap buffer over-read in mysqlnd

Noroxi assessment

Priority: Monitor (action score 24/100)

  • 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: 2.2% (FIRST EPSS); higher than 82.5% of all records.
  • Someone on the same network segment can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: PHP Group PHP 8.1.31, 8.2.24, 8.3.14; Azure Linux 3.0 ARM 8.3.14-1; Azure Linux 3.0 x64 8.3.14-1.

Low priority for now. Upgrade to PHP Group PHP 8.1.31, 8.2.24, 8.3.14; Azure Linux 3.0 ARM 8.3.14-1; Azure Linux 3.0 x64 8.3.14-1 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

Primary sources: NVD · CVE.org · FIRST EPSS

In PHP versions 8.1.* before 8.1.31, 8.2.* before 8.2.26, 8.3.* before 8.3.14, a hostile MySQL server can cause the client to disclose the content of its heap containing data from other SQL requests and possible other data belonging to different users of the same server.
