"JSP files cannot be uploaded" Error When Uploading Prompts to UCCX

[Kim Nielsen]

Hi 

We have upgraded some 12.5(1)SU3 UCCX systems to the newest ES07 due to the security CVE-2025-20354 (CVSS-score: 9.8).

After this we have discovered that we can no longer upload UCCX wav files. We can download an existing file, upload it again, and it will fail with this error: "JSP files cannot be uploaded"

We also see an error like this: "Failed to upload file with path:/1.wav/" 

From what I can read on reddit, then this is also something happening on the newest 15.1 ES01 version of UCCX. 

There I can see that if you upload your wav file to CUCM as an MoH file, and download the ulaw file again from the cucm CLI, then it would work. 

We tried that and it worked.

But uploading every file to CUCM and back is not an option. 

Any other seen this? Any other solution than uploading the wav file to CUCM?

The g711.org method that is mentioned in the Reddit thread worked for me for ONE file, then would not work again. It's beyond frustrating.

Heps,

It seems that there's gonna be an bug on this. CSCws06843. It's still not visible to the general audience. 

But there's not an fix on this. Only that you could convert the file to alaw and back to ulaw, and the upload it. 

I know that the workaround also mentioned in the Reddit link works. For us it does.

1. Upload the WAV file to CUCM as a MoH file through the Web UI

2. Download the converted WAV file to an SFTP server from the CUCM CLI

3. Upload the downloaded/converted WAV file to UCCX through the Web UI

TAC said that the BUG only was on the 12.5(1)SU3 ES07, but I would imagine that there's gonna be a similar bug for 1501 ES01.
