New Features and Improvements
Tenable Web App Scanning Scanner version 1.9.0 includes the following new features and improvements.
- Increased Selenium IDE Command Support
Expanded the support of Selenium commands that can be included in a Selenium script. All only commands are now supported except the ones related to execution flow commands (if, else, before, end, etc.), variable storage (store, store json, etc.), and window selection (selectWindow).
- Flexible Session Verification Pattern Matching Logic
Tenable Web App Scanning scanner now allows the Session Verification Pattern option for all Tenable Web App Scanning credentials to be simple text contents that the scanner will search using exact text matching in addition to regular expression matching. This facilitates the authentication setup process for cases when a regular expression is not needed.
- Improved Plugin 98044 Troubleshooting
The output of plugin 98044 (Scan aborted after being logged out) now includes the same level of detail as authentication plugins for troubleshooting why the scanner was unable to log back in to web applications. This allows users to better understand why the scanner cannot authenticate back to the target so they can address the issue by themselves.
- New Plugins
- Other Improvements
-
Sitemap results are now updated for URLs discovered with fragments, and includes the reason why the URL is not crawled but audited by the scanner browser.
-
OpenAPI / Swagger files containing control characters or non-ASCII characters can now be processed by the scanner.
-
