CVE-2025-9398 is a security vulnerability identified in the YiFang Content Management System (CMS) versions up to 2.0.5. The vulnerability resides in the function exportInstallTable located in the file app/utils/base/database/Migrate.php. This function, when manipulated remotely, leads to an information disclosure issue. Specifically, the vulnerability allows an unauthenticated attacker to remotely trigger the exportInstallTable function, potentially extracting sensitive information from the system without requiring any user interaction or privileges. The disclosed CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P) indicates that the attack can be performed over the network with low complexity, no authentication, and no user interaction, but the impact on confidentiality is limited (VC:L) with no impact on integrity or availability. The vendor has been contacted but has not responded or provided a patch, and no official fixes are currently available. Although public exploit code has been disclosed, there are no confirmed reports of exploitation in the wild at this time. The vulnerability primarily exposes information that could be leveraged for further attacks or reconnaissance by threat actors targeting systems running vulnerable versions of YiFang CMS.

For European organizations using YiFang CMS versions 2.0.0 through 2.0.5, this vulnerability poses a risk of unauthorized information disclosure. The leaked information could include database schema details, configuration data, or other sensitive internal CMS information that may aid attackers in crafting more targeted attacks such as privilege escalation, data exfiltration, or lateral movement within the network. While the direct impact on confidentiality is limited, the vulnerability’s ease of exploitation (no authentication or user interaction required) increases the risk profile. Organizations in sectors with high regulatory requirements for data protection (e.g., finance, healthcare, government) may face compliance risks if sensitive data is exposed. Additionally, the lack of vendor response and absence of patches prolong the window of exposure, increasing the likelihood of exploitation attempts. European entities relying on YiFang CMS for public-facing websites or internal portals should consider the potential reputational damage and operational disruptions that could arise from exploitation.

Given the absence of an official patch from the vendor, European organizations should implement the following specific mitigations: 1) Immediately audit all instances of YiFang CMS to identify versions 2.0.0 through 2.0.5 in use. 2) Restrict external network access to the vulnerable exportInstallTable function by implementing web application firewall (WAF) rules that block or monitor requests targeting the vulnerable endpoint or function parameters. 3) Employ network segmentation to isolate CMS servers from sensitive backend systems and databases to limit the impact of any information disclosure. 4) Conduct thorough logging and monitoring of CMS access logs to detect anomalous or suspicious requests that may indicate exploitation attempts. 5) If feasible, disable or restrict the exportInstallTable function temporarily until a patch or vendor guidance is available. 6) Engage in proactive threat hunting for indicators of compromise related to this vulnerability. 7) Consider deploying virtual patching techniques via WAF or reverse proxies to mitigate the vulnerability. 8) Plan for an upgrade or migration to a more secure CMS platform if vendor support remains unavailable.
