ID CVE-2015-7756
Summary The encryption implementation in Juniper ScreenOS 6.2.0r15 through 6.2.0r18, 6.3.0r12 before 6.3.0r12b, 6.3.0r13 before 6.3.0r13b, 6.3.0r14 before 6.3.0r14b, 6.3.0r15 before 6.3.0r15b, 6.3.0r16 before 6.3.0r16b, 6.3.0r17 before 6.3.0r17b, 6.3.0r18 before 6.3.0r18b, 6.3.0r19 before 6.3.0r19b, and 6.3.0r20 before 6.3.0r21 makes it easier for remote attackers to discover the plaintext content of VPN sessions by sniffing the network for ciphertext data and conducting an unspecified decryption attack.

Exploitability:
CWE CWE-310
CAPEC
  • Signature Spoofing by Key Recreation
    An attacker obtains an authoritative or reputable signer's private signature key by exploiting a cryptographic weakness in the signature algorithm or pseudorandom number generation and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.

description The remote host is running a version of Juniper ScreenOS that is 6.2.x prior to 6.2.0r19 or 6.3.x prior to 6.3.0r21. It is, therefore, affected by multiple vulnerabilities : - A backdoor exists that allows a remote attacker administrative access to the device over SSH or telnet. (CVE-2015-7755) - An unspecified flaw exists that allows a man-in-the-middle attacker to decrypt VPN traffic. (CVE-2015-7756) Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
