CVE-2023-51645

Summary

CVE-2023-51645 is a Directory Traversal Remote Code Execution vulnerability in Allegra's unzipFile method. This issue allows remote attackers to execute arbitrary code on affected installations, bypassing the existing authentication mechanism. The flaw arises from insufficient validation of user-supplied paths in file operations. Successful exploitation grants an attacker the ability to execute code in the context of the LOCAL SERVICE. (ZDI-CAN-22513) In simpler terms, CVE-2023-51645 refers to a security flaw in Allegra's unzipFile function. This vulnerability allows unauthorized remote users to execute arbitrary code on targeted installations by tricking the software into opening malicious files. Authentication is required for exploitation but can be bypassed. The culprit is a lack of proper path validation in file operations, which enables attackers to execute code under the LOCAL SERVICE account. (ZDI-CAN-22513) CVE-2023-51645 designates a critical flaw in Allegra's unzipFile function, enabling remote attackers to gain unauthorized access and execute code on affected systems. The vulnerability is triggered by inadequate validation of user-defined paths used in file operations. Despite requiring authentication to exploit this issue, the authentication mechanism can be circumvented. The successful execution of this attack grants an attacker the ability to execute code with LOCAL SERVICE privileges. (ZDI-CAN-22513) Allegra's unzipFile method, identified as CVE-2023-51645, is susceptible to a Remote Code Execution vulnerability. This flaw enables attackers to execute arbitrary code on affected systems by exploiting a weakness in the path validation process used during file operations. The attack requires authentication but may bypass the existing authentication mechanism, allowing an attacker to execute code under the LOCAL SERVICE account. (ZDI-CAN-22513) CVE-2023-51645 refers to a crucial vulnerability in Allegra's unzipFile method. This Remote Code Execution issue permits unauthenticated attackers to gain control over targeted installations by exploiting insufficient path validation in file operations. Despite authentication being required for exploitation, the authentication mechanism can be circumvented. The successful execution of this attack grants an attacker the ability to execute code under the LOCAL SERVICE account. (ZDI-CAN-22513)
