CVE-2018-18466

An issue was discovered in SecurEnvoy SecurAccess 9.3.502. When put in Debug mode and used for RDP connections, the application stores the emergency credentials in cleartext in the logs (present in the DEBUG folder) that can be accessed by anyone. NOTE: The vendor disputes this as a vulnerability since the disclosure of a local account password (actually an alpha numeric passcode) is achievable only when a custom registry key is added to the windows registry. This action requires administrator access and the registry key is only provided by support staff at securenvoy to troubleshoot customer issues.

Base score Version Severity Vector Exploitability Impact Score source
7.0 3.0 HIGH
CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.

Exploitation needs some favorable conditions, but not exceptional ones.
Authentication (AU:N)
No authentication is required.
Confidentiality impact (C:P)
Partial confidentiality impact.
Integrity impact (I:N)
No integrity impact.
Availability impact (A:N)
No availability impact.
