CVE-2018-0643

Vulnerability

An OS command injection vulnerability (CWE-78) exists in the panda-server component of ORCA (Online Receipt Computer Advantage) running on Ubuntu 14.04. Affected versions are 4.8.0 (panda-server) 1:1.4.9+p41-u4jma1 and earlier. The issue allows an attacker with administrator rights to execute arbitrary operating system commands through unspecified vectors [1].

Exploitation

To exploit this vulnerability, an attacker must have administrator privileges on the ORCA system and network access to the affected product. The CVSS v3 vector (AV:A/AC:L/PR:H/UI:R/S:U/C:L/I:L/A:L) indicates that user interaction is required, meaning a privileged user must perform an action that triggers the command injection. The attack complexity is low, but the attacker must be on the same adjacent network [1].

Impact

Successful exploitation enables the attacker to execute arbitrary OS commands on the server, potentially leading to partial compromise of confidentiality, integrity, and availability. The attacker can perform operations with the privileges of the application, which may include reading sensitive data, modifying files, or disrupting service [1].

Mitigation

To mitigate this vulnerability, update the ORCA software to the latest version provided by the vendor. The vendor recommends applying the appropriate update as per their advisory. No workarounds are documented; upgrading is the only known solution [1].
