CVE-2023-50612: Escalation of Privileges and Data Leakage in fit2cloud Cloud Explorer Lite

Overview

In the realm of cybersecurity, there exist vulnerabilities that pose a significant threat to data security and system integrity. One of these vulnerabilities is CVE-2023-50612, a potent Insecure Permissions vulnerability present in fit2cloud Cloud Explorer Lite version 1.4.1. This vulnerability is particularly concerning as it allows local attackers to escalate privileges and gain unauthorized access to sensitive data via the cloud accounts parameter. As more organizations leverage cloud-based solutions, understanding this vulnerability and its potential impact is critical.

How the Exploit Works

The CVE-2023-50612 exploit works by an attacker manipulating the insecure permissions of the cloud accounts parameter in fit2cloud Cloud Explorer Lite. Specifically, the attacker can escalate their privileges within the system, thus bypassing security measures and gaining access to restricted data. This exploit is particularly dangerous as it does not require any user interaction and only requires low-level privileges.

Conceptual Example Code

Although the exact method of exploiting this vulnerability will depend on the specific system configuration and the attacker’s knowledge, a conceptual example might look like this:

$ ./fit2cloud-exploit --cloud-accounts /path/to/target-account
{
"local-attacker": {
"privileges": "escalated",
"access": "granted"
}
}

This example represents an attacker using a local exploit script (`fit2cloud-exploit`) and specifying the path to the targeted cloud account (`–cloud-accounts /path/to/target-account`). The result is the attacker’s privileges being escalated (`”privileges”: “escalated”`) and gaining access to sensitive data (`”access”: “granted”`).

Mitigation Guidance

Users of fit2cloud Cloud Explorer Lite are strongly recommended to apply the vendor patch to address this vulnerability. If the patch is not immediately accessible, employing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. However, these should not be viewed as long-term solutions, and the vendor patch should be applied as soon as feasible.
