Noroxi assessment

Priority: This week (action score 68/100)

  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 94.2% (FIRST EPSS); higher than 99.8% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: apache2 (openSUSE:Tumbleweed) 2.4.23-4.1; apache2 (SUSE:Linux Enterprise Software Development Kit 11 SP4) 2.2.34-70.12.1.

Don’t wait for the next maintenance window. Upgrade to apache2 (openSUSE:Tumbleweed) 2.4.23-4.1; apache2 (SUSE:Linux Enterprise Software Development Kit 11 SP4) 2.2.34-70.12.1 or later.

modules/arch/win32/mod_isapi.c in mod_isapi in the Apache HTTP Server 2.0.37 through 2.0.63, 2.2.0 through 2.2.14, and 2.3.x before 2.3.7, when running on Windows, does not ensure that request processing is complete before calling isapi_unload for an ISAPI .dll module, which allows remote attackers to execute arbitrary code via unspecified vectors related to a crafted request, a reset packet, and "orphaned callback pointers."
