Apache HTTP Server: mod_session: Session cookie not removed during internal redirect

Noroxi assessment

Priority: Monitor (action score 30/100)

  • 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: 0.38% (FIRST EPSS).
  • 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: azl3 httpd 2.4.68-1 on Azure Linux 3.0 2.4.69-1.

Low priority for now. Upgrade to azl3 httpd 2.4.68-1 on Azure Linux 3.0 2.4.69-1 or later.
