log4shell-coraza

Log4Shell Security Lab — nginx + Coraza WAF Educational / defensive purpose : this lab contains a deliberately vulnerable app Log4j 2.14.1 and a JNDI exploit kit, ONLY for learning how to detect and block Log4Shell in an isolated environment. Do not deploy to the Internet, do not use to attack...

Coraza: URL-encoded Form Content-Type Parameters Bypass Coraza Body Inspection

Summary Coraza fails to inspect URL-encoded form bodies when their valid "Content-Type" contains a media-type parameter, for example: Content-Type: application/x-www-form-urlencoded; charset=UTF-8 An unauthenticated attacker can use this header to hide the complete form body from custom Coraza...

Coraza Body Processor Has A JSON Key Collision That Allows Unauthenticated Attackers To Bypass OWASP CRS Inspection

Summary Coraza's JSON body processor converts nested JSON properties into dot-separated "ARGSPOST" names without escaping dots contained in literal property names. Two distinct JSON properties can therefore collapse into the same Coraza variable An unauthenticated attacker can place a malicious...

Coraza: Multipart Filename* (RFC 5987) Charset Restriction Lets A Decoy Filename Bypass FILES-based Rules

Summary Coraza extracts a multipart file upload's filename using Go's standard-library "mime.ParseMediaType", which only decodes the RFC 5987/6266 extended "filename" "Content-Disposition" parameter when its declared charset is exactly "us-ascii" or "utf-8". Any other charset — including...

CVE-2026-114100

Coraza from 3.0.4 before 3.8.1 contains a request body inspection bypass because request-body processor selection compares the entire Content-Type value exactly, so URL-encoded bodies whose Content-Type carries a media-type parameter are never parsed. Unauthenticated attackers can send...

CVE-2026-114099

Coraza from 3.0.0 before 3.8.1 has a JSON body processor that flattens nested properties into dot-separated ARGSPOST names without escaping literal dots, so distinct properties collide. Unauthenticated attackers can add a later dotted property such as account.role that overwrites a malicious nest...

CVE-2026-114101

Coraza before 3.8.1 extracts multipart upload filenames with Go's mime.ParseMediaType, which silently ignores RFC 5987 filename parameters whose charset is not utf-8 or us-ascii. Unauthenticated attackers can send a decoy filename with filename=iso-8859-1''shell.php, or filename alone, so...

CVE-2026-114101 Coraza before 3.8.1 Multipart filename* Charset Handling FILES Rule Bypass

Coraza before 3.8.1 extracts multipart upload filenames with Go's mime.ParseMediaType, which silently ignores RFC 5987 filename parameters whose charset is not utf-8 or us-ascii. Unauthenticated attackers can send a decoy filename with filename=iso-8859-1''shell.php, or filename alone, so...

Coraza before 3.8.1 extracts multipart upload filenames with Go's mime.ParseMediaType, which silently ignores RFC 5987 filename parameters whose charset is not utf-8 or us-ascii. Unauthenticated attackers can send a decoy filename with filename=iso-8859-1''shell.php, or filename alone, so...

CVE-2026-114101 Coraza before 3.8.1 Multipart filename* Charset Handling FILES Rule Bypass

Coraza before 3.8.1 extracts multipart upload filenames with Go's mime.ParseMediaType, which silently ignores RFC 5987 filename parameters whose charset is not utf-8 or us-ascii. Unauthenticated attackers can send a decoy filename with filename=iso-8859-1''shell.php, or filename alone, so...

CVE-2026-114101

Coraza before 3.8.1 extracts multipart upload filenames with Go's mime.ParseMediaType, which silently ignores RFC 5987 filename parameters whose charset is not utf-8 or us-ascii. Unauthenticated attackers can send a decoy filename with filename=iso-8859-1''shell.php, or filename alone, so...

CVE-2026-114101

Coraza versions prior to 3.8.1 are vulnerable to a FILES rule bypass due to improper handling of multipart upload filenames. The issue stems from the use of Go's mime.ParseMediaType, which silently ignores RFC 5987 filename* parameters if the charset is not utf-8 or us-ascii . This allows unauthe...

CVE-2026-114100

Coraza from 3.0.4 before 3.8.1 contains a request body inspection bypass because request-body processor selection compares the entire Content-Type value exactly, so URL-encoded bodies whose Content-Type carries a media-type parameter are never parsed. Unauthenticated attackers can send...

CVE-2026-114100 Coraza from 3.0.4 before 3.8.1 Request Body Inspection Bypass via Content-Type

Coraza from 3.0.4 before 3.8.1 contains a request body inspection bypass because request-body processor selection compares the entire Content-Type value exactly, so URL-encoded bodies whose Content-Type carries a media-type parameter are never parsed. Unauthenticated attackers can send...

CVE-2026-114100 Coraza from 3.0.4 before 3.8.1 Request Body Inspection Bypass via Content-Type

Coraza from 3.0.4 before 3.8.1 contains a request body inspection bypass because request-body processor selection compares the entire Content-Type value exactly, so URL-encoded bodies whose Content-Type carries a media-type parameter are never parsed. Unauthenticated attackers can send...

CVE-2026-114100

Coraza versions 3.0.4 through 3.8.1 are susceptible to a request body inspection bypass due to a flaw in how the request-body processor selects content types. The system performs an exact comparison of the Content-Type value; consequently, URL-encoded bodies that include media-type parameters (su...
