The Information Disclosure vulnerability in Yonyou UFIDA NC arises from improper handling of sensitive data accessible through specific web endpoints. This vulnerability could potentially expose confidential information such as financial records, employee details, or other critical business data. Exploiting this vulnerability may require authenticated access to trigger the exposure, thereby increasing the risk of insider threats. Attackers can gain unauthorized insights into organizational structures or strategic metrics through the leaked information. The vulnerability indicates the need for stringent data access controls and regular audits to prevent accidental or malicious disclosures. Information disclosure vulnerabilities are pivotal concerns for organizations as they can lead to financial loss, reputational damage, and compliance violations.

Technical investigation of this vulnerability reveals that certain endpoints of the Yonyou UFIDA NC system allow information to be disclosed without adequate authorization checks. The URL paths include identifiable components like 'ActionServlet' and parameters such as 'TableSelectedID' and 'TreeSelectedID', which are intended for internal operations. These URLs may directly return sensitive data or modify the visibility of internal processes without proper authentication protocols. Exploitations involve crafting specific requests to these URLs to bypass access controls inadvertently. By observing server responses and status codes, attackers can deduce the presence and extent of exposed information. The vulnerability necessitates input validation and endpoint security enhancements.

If this vulnerability is exploited, attackers could gain unauthorized access to sensitive organizational data. The consequences might include exposure of customer information, intellectual property theft, or unlawful manipulation of business operations. Information leaks can facilitate further attacks, such as phishing or social engineering, leveraging disclosed information. Organizations may suffer from loss of trust among clients and partners due to perceived vulnerabilities in data handling practices. Non-compliance with data protection regulations could result in hefty fines or sanctions. It's imperative for affected businesses to act swiftly to protect sensitive data and maintain stakeholder confidence.
