Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Buying Buddy Buying Buddy IDX CRM allows DOM-Based XSS. This issue affects Buying Buddy IDX CRM: from n/a through 2.3.0.
AI Analysis
Technical Summary
CVE-2025-50037 is a DOM-based Cross-site Scripting (XSS) vulnerability identified in the Buying Buddy IDX CRM product, affecting versions up to 2.3.0. This vulnerability arises from improper neutralization of input during web page generation, specifically within the client-side Document Object Model (DOM) context. DOM-based XSS occurs when untrusted data is used to modify the DOM in an unsafe manner, allowing an attacker to inject malicious scripts that execute in the context of the victim's browser. The vulnerability requires that the attacker can induce a user to interact with a crafted URL or input that triggers the unsafe DOM manipulation. According to the CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L), the attack can be launched remotely over the network with low attack complexity, but requires the attacker to have some level of privileges (PR:L) and user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects components beyond the initially vulnerable component, potentially impacting the entire application or user session. The impact includes low confidentiality, integrity, and availability losses, indicating that the attacker can partially read or modify data and cause some disruption. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability is classified under CWE-79, which covers improper input neutralization leading to XSS. Buying Buddy IDX CRM is a customer relationship management system tailored for real estate IDX (Internet Data Exchange) services, which are commonly used by real estate agencies to manage listings and client interactions. The vulnerability could allow attackers to execute arbitrary scripts in the context of users interacting with the CRM, potentially leading to session hijacking, credential theft, or unauthorized actions within the CRM interface.
Potential Impact
For European organizations using Buying Buddy IDX CRM, this vulnerability poses a moderate risk. Real estate agencies and related businesses that rely on this CRM for managing client data and property listings could face targeted attacks aiming to steal sensitive client information or manipulate CRM data. The DOM-based XSS could be exploited to hijack user sessions, leading to unauthorized access to confidential client records or internal communications. Additionally, attackers might use the vulnerability to deliver phishing payloads or malware to users within the organization. Given the scope change and the ability to affect multiple users through crafted inputs, the impact could extend beyond individual users to compromise broader organizational workflows. The medium CVSS score reflects that while the vulnerability is not trivial, exploitation requires some privileges and user interaction, somewhat limiting the attack surface. However, the real estate sector in Europe is increasingly digitalized, and CRM systems are critical for business operations, making any compromise potentially damaging both financially and reputationally. Furthermore, regulatory frameworks such as GDPR impose strict requirements on protecting personal data, so exploitation leading to data breaches could result in legal and compliance consequences for affected organizations.
Mitigation Recommendations
1. Immediate mitigation should focus on input validation and sanitization on the client side to prevent unsafe DOM manipulation. Developers should implement strict encoding of all user-controllable inputs before inserting them into the DOM, using secure JavaScript APIs that avoid direct innerHTML assignments or similar unsafe methods. 2. Employ Content Security Policy (CSP) headers to restrict the execution of inline scripts and reduce the impact of XSS attacks. 3. Limit the privileges required to access vulnerable functionality within the CRM, ensuring that only trusted users can perform actions that involve dynamic DOM updates. 4. Educate users to be cautious about clicking on suspicious links or inputs that could trigger the vulnerability, as user interaction is required for exploitation. 5. Monitor web traffic and application logs for unusual patterns indicative of attempted exploitation, such as suspicious URL parameters or script injections. 6. Engage with the vendor (Buying Buddy) to obtain patches or updates as soon as they become available, and plan for prompt deployment. 7. As a temporary workaround, consider disabling or restricting features that dynamically generate web pages from user input until a fix is applied. 8. Conduct regular security assessments and penetration testing focused on client-side vulnerabilities to identify and remediate similar issues proactively.
