CVE-2023-49032 is a critical remote code execution vulnerability affecting versions of LTB Self Service Password prior to 1.5.4. The flaw arises from improper handling of the SMS verification code function, which can be hijacked by a remote attacker to redirect the verification code to an arbitrary phone number. This hijacking enables the attacker to execute arbitrary code on the affected system and gain access to sensitive information. The vulnerability is classified under CWE-94 (Improper Control of Generation of Code), indicating that the system allows injection or execution of unauthorized code. Exploitation requires no authentication or user interaction and can be performed remotely over the network, making it highly accessible to attackers. The CVSS v3.1 base score is 9.8 (critical), reflecting its high impact on confidentiality, integrity, and availability. Although no known exploits are currently reported in the wild, the severity and ease of exploitation make this vulnerability a significant threat. The lack of vendor and product specifics in the provided data suggests that LTB Self Service Password is a niche or specialized password management/self-service tool, likely used in enterprise or organizational environments to facilitate password resets via SMS verification. The vulnerability could allow attackers to bypass authentication controls, execute arbitrary commands, and exfiltrate sensitive data, potentially compromising entire user accounts and systems relying on this service.

For European organizations, this vulnerability poses a severe risk, especially for those using LTB Self Service Password as part of their identity and access management infrastructure. Successful exploitation could lead to unauthorized account takeovers, data breaches involving personal and corporate information, and disruption of authentication services. Given the critical nature of the flaw, attackers could leverage it to move laterally within networks, escalate privileges, and deploy further malware or ransomware. Sectors such as finance, healthcare, government, and critical infrastructure that rely heavily on secure password management and SMS-based verification are particularly vulnerable. The compromise of SMS verification undermines multi-factor authentication mechanisms, reducing overall security posture. Additionally, the ability to execute arbitrary code remotely can lead to full system compromise, impacting availability and operational continuity. The absence of known exploits currently does not diminish the urgency, as public disclosure may prompt rapid development of exploit code by threat actors.

Organizations should immediately upgrade LTB Self Service Password to version 1.5.4 or later, where the vulnerability is patched. In the absence of an available patch, temporarily disabling the SMS verification feature or restricting its use to trusted phone numbers can reduce exposure. Implement network-level controls such as firewall rules to limit access to the password self-service portal to trusted IP ranges. Employ monitoring and alerting for unusual activities related to SMS verification requests, including anomalous phone numbers or repeated attempts. Conduct thorough audits of authentication logs to detect potential exploitation attempts. Enhance overall authentication security by integrating alternative multi-factor authentication methods that do not rely solely on SMS, such as hardware tokens or app-based authenticators. Regularly review and update incident response plans to include scenarios involving compromise of password reset mechanisms. Finally, ensure that all systems running LTB Self Service Password are hardened and monitored for signs of code injection or unauthorized access.
