CVE-2025-58844 is a high-severity vulnerability classified as CWE-352, indicating a Cross-Site Request Forgery (CSRF) issue in the software product 'Database to Excel' developed by Subhash Kumar. This vulnerability allows an attacker to perform unauthorized actions on behalf of an authenticated user without their consent. Specifically, the CSRF flaw in this product can be leveraged to inject stored Cross-Site Scripting (XSS) payloads, which persist within the application and execute in the context of other users' browsers. The vulnerability affects versions up to 1.0, with no specific version exclusions noted. The CVSS 3.1 base score of 7.1 reflects a high-severity rating, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), scope changed (S:C), and low impacts on confidentiality, integrity, and availability (C:L/I:L/A:L). The scope change suggests that the vulnerability affects resources beyond the initially vulnerable component, potentially impacting other parts of the system or user data. The absence of known exploits in the wild suggests that while the vulnerability is serious, it may not yet be actively exploited. However, the combination of CSRF and stored XSS can enable attackers to perform actions such as stealing session tokens, manipulating user data, or spreading malware through persistent scripts. The vulnerability arises due to insufficient validation of user requests to ensure they originate from legitimate sources, allowing attackers to craft malicious web pages that trigger unintended actions when visited by authenticated users. Since the product converts database content to Excel format, it likely interacts with sensitive data, increasing the risk of data leakage or manipulation through this vulnerability.

For European organizations using 'Database to Excel', this vulnerability poses significant risks. The CSRF combined with stored XSS can lead to unauthorized data access, data corruption, or privilege escalation within the affected application. Confidentiality may be compromised if attackers extract sensitive database information or session tokens. Integrity risks arise from unauthorized modifications to data exports or application settings. Availability impact, while rated low, could occur if malicious scripts disrupt normal application operations. Given the product's role in handling database exports, organizations in sectors such as finance, healthcare, and government are particularly vulnerable due to the sensitive nature of their data. Additionally, the scope change in the CVSS vector indicates potential for broader system impact beyond the immediate application, which could affect integrated systems or workflows. The requirement for user interaction means that phishing or social engineering could be used to lure users into triggering the exploit, increasing the attack surface. European organizations must also consider compliance with GDPR and other data protection regulations, as exploitation could lead to data breaches with legal and reputational consequences.

To mitigate this vulnerability, organizations should implement several specific measures beyond generic CSRF protections. First, apply strict anti-CSRF tokens on all state-changing requests within the 'Database to Excel' application to ensure requests originate from legitimate sources. Validate the origin and referer headers as an additional check against CSRF attacks. Implement Content Security Policy (CSP) headers to reduce the impact of stored XSS by restricting script execution sources. Conduct thorough input validation and output encoding to prevent injection of malicious scripts into stored data. Since no official patches are currently available, consider isolating the application within a secure network segment and limiting access to trusted users only. Employ web application firewalls (WAFs) configured to detect and block CSRF and XSS attack patterns. Educate users about the risks of clicking on suspicious links or visiting untrusted websites while authenticated to the application. Monitor application logs for unusual activities indicative of CSRF or XSS exploitation attempts. Finally, maintain close communication with the vendor for timely patch releases and apply updates promptly once available.
