CVE-2024-21484

A flaw was found in jsrsasign, which is vulnerable to an observable discrepancy via the RSA PKCS1.5 or RSAOAEP decryption process. This flaw allows an attacker to decrypt ciphertexts. Exploiting this vulnerability requires the attacker to have access to a large number of ciphertexts encrypted wit...

CVE-2024-21484

Versions of the package jsrsasign before 11.0.0 are vulnerable to Observable Discrepancy via the RSA PKCS1.5 or RSAOAEP decryption process. An attacker can decrypt ciphertexts by exploiting the Marvin security flaw. Exploiting this vulnerability requires the attacker to have access to a large...

CVE-2024-21484

CVE-2024-21484 affects the jsrsasign JavaScript library prior to 11.0.0, where an observable discrepancy in RSA PKCS#1.5 or RSAOAEP decryption can allow an attacker to decrypt ciphertexts. The attack requires access to a large number of ciphertexts encrypted with the same key (Marvin attack). The...
