CVE-2021-31510
Description
This vulnerability allows remote attackers to execute arbitrary code on affected installations of OpenText Brava! Desktop Build 16.6.4.55. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of TIF files. 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 vulnerability to execute code in the context of the current process. Was ZDI-CAN-13675.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
A TIF file parsing out-of-bounds read in OpenText Brava! Desktop Build 16.6.4.55 allows remote code execution with user interaction.
Vulnerability
The vulnerability exists in OpenText Brava! Desktop Build 16.6.4.55 during the parsing of TIF files. The lack of proper validation of user-supplied data results in a read past the end of an allocated buffer. User interaction is required; the target must visit a malicious page or open a malicious file. [1]
Exploitation
An attacker can exploit this vulnerability by crafting a malicious TIF file and convincing a user to open it or visit a malicious page that triggers the parsing. The out-of-bounds read occurs during TIF parsing, and the attacker can leverage this to achieve code execution. [1]
Impact
Successful exploitation allows an attacker to execute arbitrary code in the context of the current process. This can lead to full compromise of confidentiality, integrity, and availability, as reflected by the CVSS score of 7.8. [1]
Mitigation
No fix or workaround is mentioned in the available reference. Users should exercise caution when opening TIF files from untrusted sources. [1]
