CVE-2025-29152 is a high-severity Cross-Site Scripting (XSS) vulnerability affecting the lemeconsultoria HCM galera.app version 4.58.0. This vulnerability allows an attacker with limited privileges (requires user authentication with low privileges) to execute arbitrary code via multiple components of the application, including but not limited to Strategic Planning Perspective Registration, Training Request, Perspective Editing, Education Registration, Hierarchical Level Registration, Decision Level Registration, Perspective Registration, Company Group Registration, Company Registration, News Registration, Employee Editing, Goal Team Registration, Learning Resource Type Registration, Learning Resource Family Registration, Learning Resource Supplier Registration, and Cycle Maintenance. The vulnerability is classified under CWE-79, indicating improper neutralization of input during web page generation, which leads to XSS. The CVSS 3.1 score is 7.6, reflecting a high impact on confidentiality with limited impact on integrity and no impact on availability. The attack vector is network-based, with low attack complexity, requiring privileges and user interaction, and the scope is changed, meaning the vulnerability affects resources beyond the vulnerable component. No known exploits are currently reported in the wild, and no patches or vendor information are provided, which may indicate the product is niche or less widely documented. The vulnerability enables an attacker to inject malicious scripts that can steal sensitive information such as session tokens, perform actions on behalf of the user, or pivot to further attacks within the affected environment.

For European organizations using lemeconsultoria HCM galera.app, this vulnerability poses a significant risk to confidentiality and user data integrity. Since the affected components cover a broad range of HR and organizational management functions, exploitation could lead to unauthorized access to sensitive employee data, strategic planning information, company structure, and internal communications. This could result in data breaches, espionage, or manipulation of organizational data. The requirement for user interaction and low privileges means that attackers could target regular users to escalate their access or perform actions unnoticed. Given the critical nature of HR and strategic data, the impact on compliance with European data protection regulations such as GDPR could be severe, potentially leading to legal and financial consequences. Additionally, the scope change indicates that the attack could affect multiple components or users beyond the initially compromised account, increasing the potential damage.

1. Immediate mitigation should include restricting access to the affected components to trusted users only and monitoring for suspicious activities involving these modules. 2. Implement strict input validation and output encoding on all user-supplied data fields within the affected components to prevent injection of malicious scripts. 3. Employ Content Security Policy (CSP) headers to reduce the impact of any potential XSS exploitation by restricting the sources from which scripts can be loaded. 4. Conduct thorough security testing and code review focusing on the identified components to identify and remediate all instances of improper input handling. 5. If possible, isolate the affected application environment from critical internal networks to limit lateral movement in case of exploitation. 6. Educate users about the risks of interacting with suspicious links or content within the application to reduce the likelihood of successful user interaction exploitation. 7. Engage with the vendor or community to obtain patches or updates as soon as they become available, and apply them promptly. 8. Implement multi-factor authentication (MFA) to reduce the risk of compromised credentials being used to exploit the vulnerability.
