CVE-2025-62977 identifies a missing authorization vulnerability in the 百度站长SEO合集 (Baidu Webmaster SEO Suite), a tool supporting push notifications to multiple search engines including Baidu, Shenma, Bing, and Toutiao. The vulnerability exists in versions up to and including 2.1.3 and allows unauthenticated attackers to access functionality that should be protected by access control lists (ACLs). This means that certain operations or data accessible through the software are not properly constrained, enabling attackers to invoke functions without proper permissions. The CVSS v3.1 base score is 5.3 (medium), with vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N, indicating network attack vector, low attack complexity, no privileges or user interaction required, unchanged scope, and limited confidentiality impact without integrity or availability effects. The vulnerability was reserved on 2025-10-24 and published on 2025-10-27, with no known exploits reported in the wild. The lack of patches currently available necessitates cautious network exposure and monitoring. The affected product is primarily used for SEO management targeting Chinese and international search engines, implying a user base that includes organizations with Chinese market interests or multilingual SEO strategies.

For European organizations, the primary impact of CVE-2025-62977 lies in the potential unauthorized access to SEO management functions or data within the 百度站长SEO合集 tool. While the vulnerability does not directly compromise system integrity or availability, unauthorized access could lead to information disclosure about SEO configurations, push notification settings, or other sensitive operational details. This could facilitate further targeted attacks or manipulation of SEO data, potentially harming brand reputation or search engine rankings. Organizations relying on this tool for managing search engine submissions, especially those integrating with Chinese search engines like Baidu or Shenma, may face increased risk. Additionally, the exposure of internal SEO strategies or configurations could provide competitive intelligence to adversaries. The medium severity suggests a moderate risk level, but the ease of exploitation without authentication increases the urgency for mitigation. European companies with subsidiaries or partnerships in China or those conducting digital marketing targeting Chinese-speaking audiences are particularly at risk.

1. Immediately restrict network access to the 百度站长SEO合集 application, limiting it to trusted internal IP addresses or VPN connections to reduce exposure. 2. Monitor logs and network traffic for unusual or unauthorized access attempts to the SEO suite's functionalities. 3. Implement additional access control mechanisms at the network or application layer, such as web application firewalls (WAFs), to block unauthorized requests. 4. Engage with the software vendor or community to obtain patches or updates addressing this vulnerability as soon as they become available. 5. If patching is delayed, consider disabling or isolating vulnerable features that do not require immediate use. 6. Conduct a security review of SEO-related workflows and data to identify any sensitive information that could be exposed and apply compensating controls. 7. Educate relevant personnel about the risks and signs of exploitation attempts related to this vulnerability. 8. For organizations using this tool in multi-national environments, ensure consistent security policies and monitoring across all deployments.
