CVE-2024-22293 is a high-severity reflected Cross-site Scripting (XSS) vulnerability identified in the Andrea Tarantini BP Profile Search product, affecting versions up to 5.5. The vulnerability arises due to improper neutralization of user input during web page generation, classified under CWE-79. Specifically, the application fails to adequately sanitize or encode input parameters before reflecting them in the web page output, allowing an attacker to inject malicious scripts. When a victim user interacts with a crafted URL or input, the malicious script executes in their browser context, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of the user. The CVSS 3.1 base score is 7.1, indicating a high severity level, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability can affect resources beyond the vulnerable component. The impact includes low confidentiality, integrity, and availability impacts individually, but combined they can be significant in the context of user session compromise or data manipulation. No known exploits are reported in the wild yet, and no patches have been linked, suggesting that remediation may still be pending or in progress. The vulnerability was published on January 31, 2024, and is tracked by Patchstack and CISA enrichment, indicating recognition by authoritative sources. The affected product, BP Profile Search by Andrea Tarantini, is a web-based profile search tool, likely used in organizational or community environments to facilitate user or profile lookups.

For European organizations using BP Profile Search, this vulnerability poses a significant risk to the confidentiality and integrity of user data and sessions. Successful exploitation could allow attackers to execute arbitrary scripts in the context of authenticated users, leading to session hijacking, theft of sensitive profile information, or unauthorized actions such as privilege escalation or data manipulation. This is particularly impactful in sectors where profile data is sensitive, such as human resources, professional networks, or membership organizations. The reflected XSS nature means attacks typically require user interaction, often via phishing or social engineering, which can be effective in targeted attacks. Additionally, the changed scope (S:C) indicates that the vulnerability could affect other components or systems connected to the vulnerable application, potentially amplifying the impact. Given the high CVSS score and the criticality of user trust and data protection under regulations like GDPR, European organizations face potential legal and reputational consequences if exploited. The absence of known exploits in the wild provides a window for proactive mitigation, but the lack of available patches necessitates immediate compensatory controls.

1. Input Validation and Output Encoding: Organizations should implement strict input validation and output encoding on all user-supplied data reflected in web pages. Employ context-aware encoding libraries to neutralize scripts. 2. Web Application Firewall (WAF): Deploy or update WAF rules to detect and block typical XSS attack patterns targeting BP Profile Search endpoints. 3. User Awareness Training: Educate users on the risks of clicking untrusted links and recognizing phishing attempts that could deliver malicious payloads exploiting this vulnerability. 4. Access Controls: Restrict access to BP Profile Search interfaces to trusted networks or authenticated users only, reducing exposure to external attackers. 5. Monitoring and Logging: Enable detailed logging of web requests and monitor for unusual patterns indicative of XSS exploitation attempts. 6. Patch Management: Engage with the vendor Andrea Tarantini to obtain patches or updates addressing CVE-2024-22293 as soon as they become available. Until then, consider temporary disabling or restricting the vulnerable functionality if feasible. 7. Content Security Policy (CSP): Implement a robust CSP header to limit the execution of unauthorized scripts in browsers, mitigating the impact of reflected XSS attacks.
