Why is it necessary to distinguish between early and currently used WebLogic versions when using the T3 protocol?

Early versions (e.g., 10.3.6.0) return version info in a `t3 <version>` format, while modern versions (e.g., 12.2.1.3.0) use a `HELO:<version>` format followed by parameters. The Python script uses regex to handle both patterns, improving accuracy. This distinction is critical for reliable detection, as discussed in the [WebLogic version detection article](/news/penetration-basics-weblogic-version-detection).
