Roundcube Webmail before 1.1.10, 1.2.x before 1.2.7, and 1.3.x before 1.3.3 allows unauthorized access to arbitrary files on the host's filesystem, including configuration files, as exploited in the wild in November 2017. The attacker must be able to authenticate at the target system with a valid username/password as the attack requires an active session. The issue is related to file-based attachment plugins and _task=settings&_action=upload-display&_from=timezone requests.

Severity, decoded
CVSS 3.1Exploitable with local access, with low privileges and no user interaction, leading to full loss of confidentiality, integrity and availability.
How the score is built
- Attack vectorAn attacker needs local access, or must trick a user into opening something on the machine.Local
- Attack complexityNo special conditions are needed; the attack works reliably.Low
- Privileges requiredThe attacker needs an ordinary user account.Low
- User interactionNo one has to click or open anything; the attack works on its own.None
- ScopeThe damage stays within the vulnerable component.Unchanged
- Confidentiality impactAn attacker can read all data the affected component holds, or the most sensitive parts of it.High
- Integrity impactAn attacker can change any data or files the affected component protects.High
- Availability impactAn attacker can take the component down completely or keep it from serving anyone.High
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:HAttackers are exploiting this in the wild.
At least one step needs hands-on work, which slows mass attacks.
A successful attack gives full control over the affected software or all of its data.
