An out-of-bounds read vulnerability in WLAvalancheService component of Ivanti Avalanche before 6.4.3, in certain conditions can allow an unauthenticated remote attacker to read sensitive information in memory.
Una vulnerabilidad de lectura fuera de los límites en el componente WLAvalancheService de Ivanti Avalanche anterior a 6.4.3, en ciertas condiciones, puede permitir que un atacante remoto no autenticado lea información confidencial en la memoria.
This vulnerability allows remote attackers to disclose sensitive information on affected installations of Ivanti Avalanche. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the WLAvalancheService, which listens on TCP port 1777 by default. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of SYSTEM.
