id: CVE-2020-9490 info: name: CVE-2020-9490 severity: medium description: Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers. author: philippedelteil tags: cve,cve2020,apache,dos reference: - https://httpd.apache.org/security/vulnerabilities_24.html - https://bugs.chromium.org/p/project-zero/issues/detail?id=2030 - https://bugs.chromium.org/p/project-zero/issues/attachmentText?aid=443369 - https://nvd.nist.gov/vuln/detail/CVE-2020-9490 requests: - method: GET path: - "{{BaseURL}}" matchers: - type: regex regex: - "Apache/2\\.4\\.([3-3][0-9]|2[0-9]|4[0-3])" part: header
