Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2024-39338)
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.
Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
2) Cryptographic issues (CVE-ID: CVE-2024-1543)
The vulnerability allows a remote attacker to gain access to sensitive information.
A side channel vulnerability with AES T-Tables is possible in a very controlled environment where precision sub-cache-line inspection can happen, such as inside an Intel SGX enclave. This can lead to recovery of the AES key. To prevent this type of attack, wolfSSL added an AES bitsliced implementation which can be enabled with the "--enable-aes-bitsliced" configure option.
3) Improper restriction of software interfaces to hardware features (CVE-ID: CVE-2024-1545)
The vulnerability allows a remote attacker to decrypt data.
The vulnerability exists due to a fault injection within the RsaPrivateDecryption() function in wolfssl/wolfcrypt/src/rsa.c. A local user can perform perform a Rowhammer fault injection and gain access to sensitive information.
