EUVDB-ID: #VU33719
Risk: Low
CVSSv4.0: 0.5 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2018-3136
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to manipulate data.
The vulnerability exists due to improper input validation within the Security component in Java SE Embedded. A remote non-authenticated attacker can exploit this vulnerability to manipulate data.

2) User enumeration via covert timing channel
EUVDB-ID: #VU255
Risk: Medium
CVSSv4.0: 6.9 [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:A/U:Green]
CVE-ID: CVE-2016-6210
CWE-ID:
CWE-200 - Information exposure
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to enumerate users on system.
The vulnerability exists in most systems where the Blowfish algorithm runs faster than SHA256/SHA512. A remote unauthenticated attacker can determine valid usernames by sending a specially crafted request with a large password (approximately 10,000 characters) to the target ssh daemon. On systems where a valid user's password has been hashed with SHA256/SHA512, the response time will be shorter for a non-existent username than for a valid username.
Successful exploitation of this vulnerability may result in disclosure or user logins.
