CVE-2024-21516: This affects versions of the package opencart/opencart from 4.0.0.0 and before 4.1.0.0. A reflected XSS issue was identified in the directory parameter of admin common/filemanager.list route. An attacker could obtain a user's token by tricking the user to click on a maliciously crafted URL. The user is then prompted to login and redirected again upon authentication with the payload automatically executing. If the attacked user has admin privileges, this vulnerability could be used as the start of a chain of exploits like Zip Slip or arbitrary file write vulnerabilities in the admin functionality. **Notes:** 1) This is only exploitable if the attacker knows the name or path of the admin directory. The name of the directory is "admin" by default but there is a pop-up in the dashboard warning users to rename it. 2) The fix for this vulnerability is incomplete. The redirect is removed so that it is not possible for an attacker to control the redirect post admin login anymore, but it is still possible to exploit this issue in admin if the user is authenticated as an admin already.
The exploitability of CVE-2024-21516 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
CVE-2024-21516 presents a challenge to exploit due to its high attack complexity, but the absence of privilege requirements still makes it a viable target for skilled attackers. A thorough security review is advised.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2024-21516, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2024-21516, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
The EPSS score estimates the probability that this vulnerability will be exploited in the near future.
EPSS Score: 0.046% (probability of exploit)
EPSS Percentile: 19.86%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 80.14% of others.
