CVE-2022-39956 – Partial rule set bypass in OWASP ModSecurity Core Rule Set for HTTP multipart requests using character encoding in the Content-Type or Content-Transfer-Encoding header
https://notcve.org/view.php?id=CVE-2022-39956
20 Sep 2022 — The OWASP ModSecurity Core Rule Set (CRS) is affected by a partial rule set bypass for HTTP multipart requests by submitting a payload that uses a character encoding scheme via the Content-Type or the deprecated Content-Transfer-Encoding multipart MIME header fields that will not be decoded and inspected by the web application firewall engine and the rule set. The multipart payload will therefore bypass detection. A vulnerable backend that supports these encoding schemes can potentially be exploited. The le... • https://coreruleset.org/20220919/crs-version-3-3-3-and-3-2-2-covering-several-cves • CWE-116: Improper Encoding or Escaping of Output CWE-863: Incorrect Authorization •

CVE-2022-39957 – Response body bypass in OWASP ModSecurity Core Rule Set via a specialy crafted charset in the HTTP Accept header
https://notcve.org/view.php?id=CVE-2022-39957
20 Sep 2022 — The OWASP ModSecurity Core Rule Set (CRS) is affected by a response body bypass. A client can issue an HTTP Accept header field containing an optional "charset" parameter in order to receive the response in an encoded form. Depending on the "charset", this response can not be decoded by the web application firewall. A restricted resource, access to which would ordinarily be detected, may therefore bypass detection. The legacy CRS versions 3.0.x and 3.1.x are affected, as well as the currently supported vers... • https://coreruleset.org/20220919/crs-version-3-3-3-and-3-2-2-covering-several-cves • CWE-116: Improper Encoding or Escaping of Output CWE-693: Protection Mechanism Failure •

CVE-2022-39958 – Response body bypass in OWASP ModSecurity Core Rule Set via repeated HTTP Range header submission with a small byte range
https://notcve.org/view.php?id=CVE-2022-39958
20 Sep 2022 — The OWASP ModSecurity Core Rule Set (CRS) is affected by a response body bypass to sequentially exfiltrate small and undetectable sections of data by repeatedly submitting an HTTP Range header field with a small byte range. A restricted resource, access to which would ordinarily be detected, may be exfiltrated from the backend, despite being protected by a web application firewall that uses CRS. Short subsections of a restricted resource may bypass pattern matching techniques and allow undetected access. Th... • https://coreruleset.org/20220919/crs-version-3-3-3-and-3-2-2-covering-several-cves • CWE-116: Improper Encoding or Escaping of Output CWE-863: Incorrect Authorization •

CVE-2022-39955 – Partial rule set bypass in OWASP ModSecurity Core Rule Set by submitting a specially crafted HTTP Content-Type header
https://notcve.org/view.php?id=CVE-2022-39955
20 Sep 2022 — The OWASP ModSecurity Core Rule Set (CRS) is affected by a partial rule set bypass by submitting a specially crafted HTTP Content-Type header field that indicates multiple character encoding schemes. A vulnerable back-end can potentially be exploited by declaring multiple Content-Type "charset" names and therefore bypassing the configurable CRS Content-Type header "charset" allow list. An encoded payload can bypass CRS detection this way and may then be decoded by the backend. The legacy CRS versions 3.0.x ... • https://coreruleset.org/20220919/crs-version-3-3-3-and-3-2-2-covering-several-cves • CWE-863: Incorrect Authorization •
