The vulnerability identified as CVE-2024-9627 affects the TeploBot – Telegram Bot for WP plugin developed by gsuvorov, used within WordPress environments to integrate Telegram bot functionalities. The root cause is a missing authorization check in the 'service_process' function, which is responsible for handling certain service requests. Due to this lack of access control, unauthenticated attackers can invoke this function remotely and retrieve the Telegram Bot Token, a secret credential that controls the bot's operations. Possession of this token allows attackers to impersonate the bot, send unauthorized messages, or manipulate bot behavior, potentially leading to misinformation, phishing, or further compromise of connected systems. The vulnerability impacts all plugin versions up to 1.3, with no authentication or user interaction required, and can be exploited over the network. The CVSS v3.1 score of 8.6 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L) indicates a high-severity issue with high confidentiality impact, limited integrity, and availability impacts. No patches or known exploits have been reported at the time of publication, but the risk remains significant given the sensitive nature of the exposed token and the ease of exploitation.

The primary impact of CVE-2024-9627 is the unauthorized disclosure of the Telegram Bot Token, which compromises the confidentiality of this sensitive credential. Attackers gaining control of the bot can impersonate it to send malicious or misleading messages, potentially damaging an organization's reputation and trust with its users. This can also facilitate phishing campaigns or social engineering attacks leveraging the trusted bot identity. Furthermore, unauthorized bot control can disrupt automated workflows or services relying on the bot, impacting availability and integrity of communications. Organizations using this plugin in their WordPress sites face increased risk of targeted attacks, data leakage, and operational disruption. The vulnerability's network-exploitable nature and lack of required privileges broaden the attack surface, making it a critical concern for any entity relying on this plugin for Telegram integration.

To mitigate CVE-2024-9627, organizations should immediately update the TeploBot – Telegram Bot for WP plugin to a version that includes proper authorization checks once such a patch is released by the vendor. Until a patch is available, administrators should consider disabling the plugin or restricting access to the affected 'service_process' endpoint via web application firewalls (WAFs) or server-level access controls to prevent unauthenticated requests. Monitoring network traffic for unusual requests to the plugin's endpoints and scanning logs for unauthorized access attempts can help detect exploitation attempts. Additionally, if the Telegram Bot Token is suspected to be compromised, it should be regenerated via the Telegram BotFather interface and the old token revoked to prevent misuse. Implementing least privilege principles for bot permissions and isolating bot functions can further reduce potential damage. Regular security audits and vulnerability scanning of WordPress plugins are recommended to identify and remediate similar issues proactively.
