CVE-2024-40725: Apache HTTP Server: source code disclosure with handlers configured via AddType

Noroxi assessment

Priority: Monitor (action score 22/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 4.4% (FIRST EPSS); higher than 91.4% 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.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: Apache Software Foundation Apache HTTP Server 2.4.62; azl3 httpd 2.4.61-1 on Azure Linux 3.0 2.4.62-1; azl3 httpd 2.4.62-1 on Azure Linux 3.0 2.4.62-1.

Low priority for now. Upgrade to Apache Software Foundation Apache HTTP Server 2.4.62; azl3 httpd 2.4.61-1 on Azure Linux 3.0 2.4.62-1; azl3 httpd 2.4.62-1 on Azure Linux 3.0 2.4.62-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

A partial fix for  CVE-2024-39884 in the core of Apache HTTP Server 2.4.61 ignores some use of the legacy content-type based configuration of handlers. "AddType" and similar configuration, under some circumstances where files are requested indirectly, result in source code disclosure of local content. For example, PHP scripts may be served instead of interpreted. Users are recommended to upgrade to version 2.4.62, which fixes this issue.
