The information leak threats are certainly new, but the education and messaging from security evangelists (and even just anyone trying to educate an older or less security-savvy family member) doesn’t change.

cmseasy v7.7.7.7 20230520 was discovered to contain a path traversal vulnerability via the add_action method at lib/admin/language_admin.php. This vulnerability allows attackers to execute arbitrary code and perform a local file inclusion.

**The following mitigating factors might be helpful in your situation:** Exploitation of the security issues in the drivers requires multiple steps, the primary of which is the ability of an attacker to direct a client (that they want to compromise) to connect to their malicious server. If your environment only connects to known, trusted servers and there is no ability to direct existing connection configurations to the wrong server (e.g., you use TLS encryption with certificate validation), these issues can not be exploited.

**How could an attacker exploit this vulnerability?** An attacker could exploit the vulnerability by tricking an authenticated user into attempting to connect to a malicious SQL server via OLEDB, which could result in the server receiving a malicious networking packet. This could allow the attacker to execute code remotely on the client.

**According to the CVSS metric, the attack vector is local (AV:L). Why does the CVE title indicate that this is a remote code execution?** The word **Remote** in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. For example, when the score indicates that the **Attack Vector** is **Local** and **User Interaction** is **Required**, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer.
