Description
This security bulletin contains information about 2 vulnerabilities.
1) Man-in-the-middle attack (CVE-ID: CVE-2015-4000)
CWE-ID: CWE-300 - Channel Accessible by Non-Endpoint ('Man-in-the-Middle')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:A/U:Green
The vulnerability allows a remote attacker to decrypt TLS connections in certain situations.
The vulnerability exists due to boundary error when parsing HTTP requests. A remote unauthenticated attacker can conduct a man-in-the-middle attack that can lead to the target system to downgrade the Diffie-Hellman algorithm to 512-bit export-grade cryptography.
Successful exploitation of this vulnerability may result in modification of authentication information
2) Information disclosure (CVE-ID: CVE-2015-2808)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to obtain potentially sensitive information communicated by target system.
The vulnerability exists due to access control error. A remote unauthenticated attacker can obtain RC4 encrypted data and conduct a brute-force key guessing attack by monitoring TLS network traffic.
Successful exploitation of this vulnerability may result in disclosure of system information.
