CVE-2009-1903
The PDF XSS protection feature in ModSecurity before 2.5.8 allows remote attackers to cause a denial of service (Apache httpd crash) via a request for a PDF file that does not use the GET method.
Does this matter?
Lower severity and a low EPSS score (3.03%). Track it; it rarely justifies an emergency change on its own.
