Security Vulnerability Detected

At the heart of our discussion is the detection of a security vulnerability linked to the clone dependency. Classified as MEDIUM in criticality, this issue carries a significant risk level that warrants immediate attention and remediation efforts. The assigned score, while currently undefined, underscores the potential for exploitation and the need for proactive measures to safeguard systems and data. Understanding the nature of this vulnerability is the first step towards effectively mitigating its impact.

Dependency: clone

The vulnerability specifically affects the clone dependency, highlighting the importance of scrutinizing third-party libraries and components integrated into software projects. Dependencies, while often essential for functionality and efficiency, can introduce vulnerabilities if not properly managed and monitored. Regularly updating and patching dependencies is crucial to address known security flaws and prevent potential exploits. The clone dependency, in this context, serves as a critical focal point for security assessments and remediation strategies.

Criticality: MEDIUM (Score: undefined)

The MEDIUM criticality rating assigned to this vulnerability indicates a moderate level of risk. While not as severe as critical or high-level vulnerabilities, it still poses a significant threat that cannot be ignored. A medium-level vulnerability typically implies that an attacker could exploit the flaw to gain unauthorized access, potentially leading to data breaches, system compromise, or other adverse outcomes. The undefined score further emphasizes the urgency of investigating and addressing this vulnerability to prevent potential exploitation.

Vulnerability Details

To fully grasp the implications of this vulnerability, it's essential to delve into the specifics. The vulnerability, identified as CVE-2023-0958, presents a clear and present danger, particularly within WordPress environments utilizing Inisev plugins. Understanding the name, description, and scope of the vulnerability is crucial for formulating an effective mitigation strategy.

Name: CVE-2023-0958

The vulnerability is officially designated as CVE-2023-0958, a unique identifier within the Common Vulnerabilities and Exposures (CVE) system. This designation allows security professionals and developers to track and reference the specific vulnerability across various databases, security advisories, and remediation efforts. The CVE identifier provides a standardized way to communicate about vulnerabilities, ensuring clarity and consistency in addressing security concerns.

Description:

The vulnerability stems from a missing capability check on the handle_installation function within several WordPress plugins developed by Inisev. This function is invoked via the inisev_installation AJAX action, creating a potential entry point for unauthorized access. The absence of proper access controls means that authenticated attackers with minimal permissions, such as subscribers, can exploit this flaw to install select plugins from Inisev on vulnerable sites. This unauthorized installation can lead to a variety of security risks, including the introduction of malicious code, data compromise, and disruption of services. It's also noted that CVE-2023-38514 appears to be a duplicate of this vulnerability, underscoring the widespread nature and potential impact of the issue.

This vulnerability highlights a significant security gap in the affected plugins, making it imperative for site administrators and developers to take immediate action. The ability for low-privileged users to install plugins without proper authorization opens the door to numerous malicious activities, potentially compromising the integrity and security of the entire WordPress installation. Therefore, understanding the specifics of this vulnerability is crucial for developing and implementing effective countermeasures.

Impact and Scope

The impact of this vulnerability is substantial, particularly for websites running the affected Inisev plugins. An attacker exploiting this flaw could potentially gain control over the site by installing malicious plugins, leading to data theft, website defacement, or other harmful activities. The scope of the vulnerability is broad, affecting multiple plugins and potentially a large number of WordPress websites. This widespread impact necessitates a coordinated response, involving plugin developers, website administrators, and security professionals working together to identify and patch affected systems.

Metadata Analysis

The metadata associated with this vulnerability offers valuable insights into its nature and potential impact. Key elements such as vulnerability identifiers, publication and modification dates, CVSS score, and affected components provide a comprehensive understanding of the issue. Analyzing this metadata is crucial for prioritizing remediation efforts and implementing appropriate security measures.

Key Metadata Components

  • Vulnerability Identifiers: The primary identifier, CVE-2023-0958, allows for consistent tracking and referencing of the vulnerability. This identifier is crucial for security advisories, patch management, and communication among security professionals.
  • Published and Last Modified Dates: These dates provide a timeline of the vulnerability's disclosure and any subsequent updates. The published date indicates when the vulnerability was first made public, while the last modified date reflects any changes or updates to the vulnerability information. These dates are essential for understanding the recency and relevance of the vulnerability.
  • Version: The version number, in this case, 3.1, indicates the specific version of the vulnerability information. This is important for ensuring that you are referencing the most current and accurate details.
  • CVSS Vector String: The CVSS (Common Vulnerability Scoring System) vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N) provides a detailed breakdown of the vulnerability's characteristics. Each component of the vector string represents a specific attribute of the vulnerability, such as attack vector, attack complexity, privileges required, and impact on confidentiality, integrity, and availability. Understanding the CVSS vector string is crucial for accurately assessing the severity and potential impact of the vulnerability.
  • Base Score and Severity: The base score of 4.3 and severity rating of MEDIUM provide an overall assessment of the vulnerability's risk level. The base score is calculated based on the inherent characteristics of the vulnerability, while the severity rating categorizes the vulnerability's potential impact (e.g., critical, high, medium, low).
  • Attack Vector and Complexity: The attack vector (NETWORK) indicates that the vulnerability can be exploited remotely over a network. The attack complexity (LOW) suggests that the vulnerability is relatively easy to exploit. These factors highlight the accessibility and ease of exploitation, underscoring the urgency of addressing the vulnerability.
  • Privileges Required: The privileges required (LOW) indicate that an attacker with minimal permissions can exploit the vulnerability. This is particularly concerning as it means even low-level users can potentially cause harm.
  • User Interaction: The user interaction (NONE) specifies that no user interaction is required to exploit the vulnerability. This means that an attacker can exploit the vulnerability without any action from the user, increasing the potential for automated attacks.
