A vulnerability, which was classified as critical, has been found in jsrsasign Package up to 8.0.17 on Node.js (JavaScript Library). Affected by this issue is some unknown functionality of the component RSA PKCS1 Handler. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is integrity, and availability. CVE summarizes:

An issue was discovered in the jsrsasign package before 8.0.18 for Node.js. Its RSA PKCS1 v1.5 decryption implementation does not detect ciphertext modification by prepending '\0' bytes to ciphertexts (it decrypts modified ciphertexts without error). An attacker might prepend these bytes with the goal of triggering memory corruption issues.

The weakness was shared 06/22/2020. This vulnerability is handled as CVE-2020-14967 since 06/22/2020. The exploitation is known to be difficult. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available.
