CVE-2021-35235: ASP.NET Debug Feature Enabled

• Severity: medium (CVSS 5.3 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 1.3% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2021-10-27 · updated 2026-06-17
• Weakness: CWE-11

Description

The ASP.NET debug feature is enabled by default in Kiwi Syslog Server 9.7.2 and previous versions. ASP.NET allows remote debugging of web applications, if configured to do so. Debug mode causes ASP.NET to compile applications with extra information. The information enables a debugger to closely monitor and control the execution of an application. If an attacker could successfully start a remote debugging session, this is likely to disclose sensitive information about the web application and supporting infrastructure that may be valuable in targeting SWI with malicious intent.

Affected products

• SolarWinds Kiwi Syslog Server: through 9.7.2
