CVE-2015-6358

Multiple Cisco embedded devices use hardcoded X.509 certificates and SSH host keys embedded in the firmware, which allows remote attackers to defeat cryptographic protection mechanisms and conduct man-in-the-middle attacks by leveraging knowledge of these certificates and keys from another installation, aka Bug IDs CSCuw46610, CSCuw46620, CSCuw46637, CSCuw46654, CSCuw46665, CSCuw46672, CSCuw46677, CSCuw46682, CSCuw46705, CSCuw46716, CSCuw46979, CSCuw47005, CSCuw47028, CSCuw47040, CSCuw47048, CSCuw47061, CSCuw90860, CSCuw90869, CSCuw90875, CSCuw90881, CSCuw90899, and CSCuw90913.

CVSS metrics for this CVE.

Base score Version Severity Vector Exploitability Impact Score source
5.9 3.0 MEDIUM
CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
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:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.

4.3 2.0 MEDIUM
AV:N/AC:M/Au:N/C:P/I:N/A:N Click to expand
Access vector (AV:N)
Can be exploited remotely over network reachability.
Access complexity (AC:M)
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.
