Fixed In:

Opened: Feb 15, 2018
Severity: 3-Major

Symptoms

If JavaScript code contains multi-byte character which contains 0x0A in the last byte after conversion to UTF-32 form, then this character is handled as NEW LINE by Portal Access server-side JavaScript parser. If NEW LINE is not valid in this place, JavaScript code cannot be parsed.

Impact

Web application may not work correctly.

Conditions

JavaScript code with multi-byte character which contains 0x0A in the last byte after conversion to UTF-32 form, for example: //? aa bb (?) gives (4E 0A) in UTF32 form. So this line is processed as the following TWO lines: // aa bb The second line is not a valid JavaScript code.

Workaround

There is no workaround at this time.

Fix Information

Now Portal Access JavaScript parser handles multi-byte characters correctly.
