CVE-2006-2058

CVE-2006-2058 describes an argument injection vulnerability in Avant Browser 10.1 Build 17. This flaw allows user-assisted remote attackers to manipulate command line arguments for an invoked mail client, such as Microsoft Outlook, by injecting double quotes into a mailto: scheme handler, potentially leading to arbitrary file attachments. The vulnerability has a CVSS score of 5.0 (Medium), indicating a network-based attack with low complexity and no authentication required, primarily impacting confidentiality. While the specific impact is noted as potentially allowing arbitrary filenames as attachments, the broader implications of argument injection could be more severe depending on the mail client. There is no evidence of active exploitation, and no exploit code is publicly available on platforms like Metasploit or ExploitDB. The vulnerability has received minimal community attention and media coverage, suggesting it is not widely discussed or exploited.
