Vulnerability Details
The Buzz Club – Night Club, DJ and Music Festival Event WordPress Theme theme is vulnerable to unauthorized modification of data due to a missing capability check on the 'cmsmasters_hide_admin_notice' function in all versions up to, and including, 2.0.4.
This vulnerability allows authenticated attackers with Subscriber-level access and above to modify the option values on the WordPress site. This can create an error on the site, leading to denial of service for legitimate users or allow attackers to manipulate registration values.
The CVSS score for this vulnerability is 4.3, which reflects a medium severity level. The attack vector is classified as 'NETWORK', the attack complexity as 'LOW', and the privileges required are 'LOW'. The integrity impact is noted as 'LOW', while confidentiality and availability impacts are 'NONE'.
Technical Analysis
The root cause of the vulnerability lies in the lack of appropriate checks within the function 'cmsmasters_hide_admin_notice'. Attackers can exploit this flaw to alter settings without adequate permissions.
The attack vector involves authenticated access, meaning that an attacker must have a valid login to the WordPress site with at least Subscriber-level privileges. The attack complexity is low due to the straightforward nature of the exploit.
No user interaction is required, which increases the risk of exploitation. Given the low privileges required, even a basic attacker could potentially leverage this vulnerability.
The integrity impact is classified as low, meaning that while attackers can modify data, the overall security model is not severely compromised. However, the potential for denial of service due to erroneous settings could affect the availability of the site.
Risk & Impact Analysis
Risk to organizations includes the possibility of denial of service, which can disrupt legitimate user access and affect business operations. The vulnerability has a moderate exploitability score, indicating that while it may not be actively targeted, it remains a risk.
Given that this vulnerability is present in a widely used WordPress theme, the potential blast radius could be significant. Organizations using the Buzz Club theme should be particularly vigilant to ensure they are not impacted by this vulnerability.
The urgency for remediation is categorized as medium. Organizations should address this vulnerability in their priority patch cycle to mitigate potential risks.
