CVE-2023-24529 in BSP Application
Summary
by MITRE • 02/14/2023
Due to lack of proper input validation, BSP application (CRM_BSP_FRAME) - versions 700, 701, 702, 731, 740, 750, 751, 752, 75C, 75D, 75E, 75F, 75G, 75H, allow malicious inputs from untrusted sources, which can be leveraged by an attacker to execute a Reflected Cross-Site Scripting (XSS) attack. As a result, an attacker may be able to hijack a user session, read and modify some sensitive information.

The vulnerability identified as CVE-2023-24529 affects the BSP application CRM_BSP_FRAME across multiple versions including 700, 701, 702, 731, 740, 750, 751, 752, 75C, 75D, 75E, 75F, 75G, and 75H. This security flaw stems from inadequate input validation mechanisms within the application's processing pipeline, creating a pathway for malicious actors to inject harmful code through user-supplied data. The vulnerability specifically manifests as a reflected cross-site scripting issue, where attacker-controlled input is immediately reflected back to users without proper sanitization or encoding, making it particularly dangerous in web-based environments where user interaction is prevalent.
The technical nature of this vulnerability places it squarely within CWE-79, which defines Cross-Site Scripting as a weakness that occurs when an application includes untrusted data in a new web page without proper validation or encoding, or user-controllable data in a context that supports script execution. The flaw allows attackers to craft malicious payloads that, when executed by unsuspecting users, can hijack active sessions and gain unauthorized access to sensitive information. The reflected nature of this XSS attack means that the malicious script is reflected off the web server rather than being stored, making it more difficult to detect and prevent through traditional security measures.
The operational impact of this vulnerability extends beyond simple data theft, as successful exploitation can lead to complete session hijacking and unauthorized access to corporate resources. An attacker could potentially gain access to sensitive customer data, manipulate business processes, or even escalate privileges within the system. The vulnerability affects the core functionality of the CRM_BSP_FRAME application, which is likely used for customer relationship management and business process support, making it a critical target for exploitation. The wide range of affected versions suggests this is a persistent flaw that has not been adequately addressed in the product lifecycle, potentially leaving organizations exposed across multiple deployment scenarios.
Organizations utilizing affected versions of the BSP application should prioritize immediate remediation through official patches provided by the vendor, as recommended by the ATT&CK framework's approach to mitigating web application vulnerabilities. The mitigation strategy should include implementing robust input validation, output encoding, and Content Security Policy (CSP) headers to prevent script execution in user-controllable contexts. Additionally, security teams should conduct comprehensive vulnerability assessments to identify any potential exploitation attempts and implement network-based protections such as web application firewalls to detect and block malicious payloads. Regular security testing and code reviews should be mandated to prevent similar issues from emerging in future development cycles, aligning with industry best practices for secure software development lifecycle implementation.
