OrbiTeam BSCW Classic before 7.4.3 allows authenticated remote code execution (RCE) during archive extraction via attacker-supplied Python code in the class attribute of a .bscw file. This is fixed in 5.0.12, 5.1.10, 5.2.4, 7.3.3, and 7.4.3.

OrbiTeam BSCW Classic before 7.4.3 allows exportpdf authenticated remote code execution (RCE) via XML tag injection because reportlab\platypus\paraparser.py (reached via bscw.cgi op=_editfolder.EditFolder) calls eval on attacker-supplied Python code. This is fixed in 5.0.12, 5.1.10, 5.2.4, 7.3.3, and 7.4.3.

OrbiTeam BSCW before 5.0.8 allows remote attackers to obtain sensitive metadata via the inf operations (op=inf) to an object in pub/bscw.cgi/.

config_converters.py in BSCW (Basic Support for Cooperative Work) 3.x and versions before 4.06 allows remote attackers to execute arbitrary commands via shell metacharacters in the file name during filename conversion.

The default configuration of BSCW (Basic Support for Cooperative Work) 3.x and possibly version 4 enables user self registration, which could allow remote attackers to upload files and possibly join a user community that was intended to be closed.

BSCW groupware system 3.3 through 4.0.2 beta allows remote attackers to read or modify arbitrary files by uploading and extracting a tar file with a symlink into the data-bag space.
