CVE-2008-3422: Multiple cross-site scripting (XSS) vulnerabilities in the ASP.net class libraries in Mono 2.0 and earlier...

Multiple cross-site scripting (XSS) vulnerabilities in the ASP.net class libraries in Mono 2.0 and earlier allow remote attackers to inject arbitrary web script or HTML via crafted attributes related to (1) HtmlControl.cs (PreProcessRelativeReference), (2) HtmlForm.cs (RenderAttributes), (3) HtmlInputButton (RenderAttributes), (4) HtmlInputRadioButton (RenderAttributes), and (5) HtmlSelect (RenderChildren).

Security readout for executives and security teams

This is an old Mono ASP.NET library issue where web applications could fail to encode certain HTML attributes. If an application exposed affected controls to attacker-controlled input, a remote attacker could inject script or HTML into a victim's browser. The business risk is mainly legacy internet-facing services still running Mono 2.0 or earlier. Likely exposure is limited to legacy ASP.NET applications running on Mono 2.0 or earlier, especially if reachable by browsers and processing attacker-controlled attribute values. Modern Mono or migrated .NET stacks are not shown as affected by the supplied sources. Medium priority unless legacy Mono-hosted web applications are internet-facing or business-critical. The issue is old and not KEV-listed, but XSS can still affect users, sessions, and trust if vulnerable systems remain online. Mitigation focus: Identify any internet-facing applications using Mono 2.0 or earlier ASP.NET libraries.; Review vendor advisories from Mono, SUSE, and Ubuntu for fixed package guidance.; Upgrade affected Mono packages or retire legacy Mono-hosted ASP.NET applications..
