CVE-2026-1179 identifies a SQL injection vulnerability in Yonyou KSOA version 9.0, located in the HTTP GET parameter handler for the 'folderid' argument within the /kmf/user_popedom.jsp file. This vulnerability arises from insufficient input sanitization, allowing an attacker to inject malicious SQL statements remotely without requiring authentication or user interaction. The injection can lead to unauthorized data access, modification, or deletion, potentially compromising confidentiality, integrity, and availability of backend databases. The vulnerability has a CVSS 4.0 score of 6.9, reflecting medium severity with network attack vector, low complexity, no privileges or user interaction needed, and limited scope impact. The exploit code is publicly available, increasing the risk of exploitation despite no confirmed active attacks. The vendor Yonyou has not issued a patch or responded to disclosure, leaving affected systems exposed. This vulnerability impacts organizations relying on Yonyou KSOA 9.0 for enterprise resource planning or business process management, especially where sensitive data is stored or processed. The lack of vendor response necessitates immediate defensive measures by users to mitigate risk.

For European organizations, exploitation of CVE-2026-1179 could result in unauthorized access to sensitive corporate data, including intellectual property, financial records, or personal data protected under GDPR. Attackers could manipulate or exfiltrate data, leading to data breaches, regulatory penalties, and reputational damage. The ability to execute arbitrary SQL commands remotely without authentication heightens the risk of widespread compromise. Additionally, attackers could disrupt business operations by corrupting databases or causing denial of service. Organizations in sectors such as finance, manufacturing, and government using Yonyou KSOA 9.0 are particularly vulnerable. The public availability of exploit code increases the likelihood of opportunistic attacks, especially against unpatched or poorly monitored systems. The absence of vendor patches means organizations must rely on internal controls and compensating security measures to reduce exposure.

Given the absence of an official patch, European organizations should implement immediate mitigations including: 1) Deploy web application firewalls (WAFs) with custom rules to detect and block malicious SQL injection payloads targeting the 'folderid' parameter in /kmf/user_popedom.jsp. 2) Conduct thorough input validation and sanitization on all user-supplied parameters, especially 'folderid', to prevent injection. 3) Restrict database user permissions to the minimum necessary to limit the impact of any injection. 4) Monitor database logs and web server logs for unusual queries or access patterns indicative of exploitation attempts. 5) Isolate affected systems within segmented network zones to reduce lateral movement risk. 6) Consider temporary disabling or restricting access to the vulnerable component if feasible until a patch or vendor guidance is available. 7) Engage with Yonyou support channels persistently for updates or patches. 8) Educate security teams on this vulnerability and incorporate detection signatures into intrusion detection systems. These steps go beyond generic advice by focusing on specific parameter hardening, monitoring, and network segmentation tailored to this vulnerability.
