Forge has signature forgery in RSA-PKCS due to ASN.1 extra field
Platform
nodejs
Component
node-forge
Fixed in
1.4.0
Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.4.0, RSASSA PKCS#1 v1.5 signature verification accepts forged signatures for low public exponent keys (e=3). Attackers can forge signatures by stuffing “garbage” bytes within the ASN structure in order to construct a signature that passes verification, enabling Bleichenbacher style forgery. This issue is similar to CVE-2022-24771, but adds bytes in an addition field within the ASN structure, rather than outside of it. Additionally, forge does not validate that signatures include a minimum of 8 bytes of padding as defined by the specification, providing attackers additional space to construct Bleichenbacher forgeries. Version 1.4.0 patches the issue.
How to fix
Actualice la biblioteca Forge a la versión 1.4.0 o superior. Esta versión corrige la vulnerabilidad de falsificación de firmas RSA-PKCS. Para actualizar, utilice el gestor de paquetes npm: `npm install node-forge@latest`.
