CVE-2022-31781

Regular Expression Denial of Service (ReDoS) in maven/org.apache.tapestry/tapestry-core

Identifiers

CVE-2022-31781

Package Slug

maven/org.apache.tapestry/tapestry-core

Vulnerability

Regular Expression Denial of Service (ReDoS)

Description

Apache Tapestry up to version 5.8.1 is vulnerable to Regular Expression Denial of Service (ReDoS) in the way it handles Content Types. Specially crafted Content Types may cause catastrophic backtracking, taking exponential time to complete. Specifically, this is about the regular expression used on the parameter of the org.apache.tapestry5.http.ContentType class. Apache Tapestry 5.8.2 has a fix for this vulnerability. Notice the vulnerability cannot be triggered by web requests in Tapestry code alone. It would only happen if there's some non-Tapestry codepath passing some outside input to the ContentType class constructor.

Affected Versions

All versions before 5.8.2

Solution

Upgrade to version 5.8.2 or above.
