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...

Spoofing

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...

jsrsasign Security Vulnerabilities

The jsrsasign package is an open source cryptographic library from the individual developer Kenji Urashima in Japan. A security vulnerability exists in jsrsasign versions prior to 11.0.0, which stems from the susceptibility to Observable Discrepancy in the decryption process of RSA PKCS1.5 or...

Medium: nss

Issue Overview: It was discovered that the numerical library used in NSS for RSA cryptography leaks information whether high order bits of the RSA decryption result are zero. This information can be used to mount a Bleichenbacher or Manger like attack against all RSA decryption operations. As the...
