CVE-2020-36666: The directory-pro WordPress plugin before 1.9.5, final-user-wp-frontend-user-profiles WordPress plugin before 1.2.2, producer-retailer WordPress plugin through TODO, photographer-directory WordPress plugin before 1.0.9, real-estate-pro WordPress plugin before 1.7.1, institutions-directory WordPress plugin before 1.3.1, lawyer-directory WordPress plugin before 1.2.9, doctor-listing WordPress plugin before 1.3.6, Hotel Listing WordPress plugin before 1.3.7, fitness-trainer WordPress plugin before 1.4.1, wp-membership WordPress plugin before 1.5.7, sold by the same developer (e-plugins), do not implementing any security measures in some AJAX calls. For example in the file plugin.php, the function iv_directories_update_profile_setting() uses update_user_meta with any data provided by the ajax call, which can be used to give the logged in user admin capabilities. Since the plugins allow user registration via a custom form (even if the blog does not allow users to register) it makes any site using it vulnerable.
The exploitability of CVE-2020-36666 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-2020-36666 presents an accessible attack vector with minimal effort required. Restricting access controls and implementing security updates are critical to reducing exploitation risks.
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-2020-36666, 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-2020-36666, 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: 0.114% (probability of exploit)
EPSS Percentile: 46.9%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 53.1% of others.
