Detailsinfo

A vulnerability, which was classified as problematic, has been found in hapijs Content up to 6.0.2. Affected by this issue is the function Content.disposition of the component Header Parsing. The manipulation with an unknown input leads to a infinite loop vulnerability. Using CWE to declare the problem leads to CWE-835. The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop. Impacted is availability. CVE summarizes:

@hapi/content provides HTTP Content-* header parsing. From 3.0.6 until 6.0.3, Content.disposition() uses an unanchored parameter-name expression in a global regular-expression scan, causing repeated failed matching over the remaining input when a Content-Disposition parameter contains a long token without an equals sign. The resulting quadratic processing can block the Node.js event loop before route handlers or validation when @hapi/pez parses multipart/form-data headers, including unauthenticated hapi routes with payload.multipart enabled, and also affects applications that pass untrusted headers directly to Content.disposition(). This issue is fixed in @hapi/content version 6.0.3.
