Description
This security bulletin contains information about 1 vulnerability.
1) CRLF injection (CVE-ID: N/A)
CWE-ID: CWE-93 - Improper Neutralization of CRLF Sequences ('CRLF Injection')
CVSSv4: 4.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote user to redirect listeners to an attacker-controlled stream displayed under the victim station's name by injecting entries into its public PLS playlist.
The vulnerability exists due to improper neutralization of CRLF sequences in AzuraCast's public PLS playlist generation when embedding mount or remote relay display_name values into TitleN= lines. A remote user can set a display_name containing carriage returns, line feeds, and additional FileN= and TitleN= entries using the Station:MountPoints or Station:RemoteRelays permission to spoof playlist content when a listener downloads and opens the playlist in a media player that honors the injected entries.
