CVE-2024-4936: Remote File Inclusion Vulnerability in Canto Plugin for WordPress
Overview:
The Canto plugin for WordPress, up to and including version 3.0.8, has been identified with a critical vulnerability labeled CVE-2024-4936. This vulnerability allows unauthenticated attackers to perform Remote File Inclusion (RFI) attacks via the 'abspath' parameter. By exploiting this vulnerability, attackers can include remote files on the server, potentially leading to arbitrary code execution. However, it's crucial to note that successful exploitation relies on the 'allow_url_include' directive being enabled on the target site's PHP configuration.
Details:
The Canto plugin, designed for WordPress websites, offers functionalities related to content management and media organization. However, a flaw in versions up to 3.0.8 allows attackers to manipulate the 'abspath' parameter, leading to the inclusion of remote files. This vulnerability can be exploited by crafting a malicious request to the affected WordPress site, where the attacker specifies a remote file to be included. If successful, the attacker can execute arbitrary code on the server, potentially compromising the entire system.
Risk Assessment:
With a CVSS (Common Vulnerability Scoring System) score of 9.8, this vulnerability is classified as critical. The presence of 'allow_url_include' being enabled further escalates the risk, as it facilitates remote file inclusion attacks. Websites utilizing the vulnerable versions of the Canto plugin are at significant risk of unauthorized code execution and potential data breaches.
Mitigation:
Immediate mitigation steps include updating the Canto plugin to version 3.1 or higher, where the vulnerability has been patched. Additionally, website administrators should ensure that 'allow_url_include' is disabled in the PHP configuration, which can prevent exploitation even if the plugin is not immediately updated. Regular security audits and monitoring are essential to detect and mitigate similar vulnerabilities in WordPress plugins.
CVE-2024-1094: Unauthorized Data Modification in Timetics Plugin for WordPress
Overview:
The Timetics plugin for WordPress, up to version 1.0.21, is susceptible to CVE-2024-1094, a vulnerability allowing unauthorized modification of data. This vulnerability arises from a missing capability check in the 'make_staff()' function, enabling unauthenticated attackers to grant users staff permissions without proper authorization.
Details:
Timetics is an AI-powered appointment booking and calendar scheduling plugin designed for WordPress websites. However, versions up to 1.0.21 contain a flaw in the permission-handling mechanism. Specifically, the 'make_staff()' function lacks a proper capability check, allowing attackers to bypass access controls and grant staff permissions to unauthorized users. This could lead to unauthorized access to sensitive functionalities and data within the WordPress site.
Risk Assessment:
The vulnerability associated with CVE-2024-1094 carries a CVSS score of 7.3, categorizing it as high risk. Although exploitation requires some level of user interaction, the potential impact on the integrity and confidentiality of data within the WordPress site is significant. Attackers could exploit this vulnerability to manipulate staff permissions, potentially compromising sensitive information or disrupting essential functionalities.
Mitigation:
Website administrators are advised to update the Timetics plugin to version 3.1 or higher, where the vulnerability has been addressed. Additionally, implementing proper access controls and capability checks within the plugin's codebase can help prevent similar vulnerabilities in the future. Regular security audits and monitoring are crucial for identifying and addressing potential security weaknesses in WordPress plugins and themes.
