When such occasions are exploited, a remote user is able to execute arbitrary code under the webserver user id on the web server hosting the mantis system. Jeroen Latour discovered that Mantis did not check all user input, especially if they do not come directly from form fields. This opens up a wide variety of SQL poisoning vulnerabilities on systems without magic_quotes_gpc enabled. Most of these vulnerabilities are only exploitable in a limited manner, since it is no longer possible to execute multiple queries using one call to mysql_query(). There is one query which can be tricked into changing an account's access level. Jeroen Latour also reported that it is possible to instruct Mantis to show reporters only the bugs that they reported, by setting the limit_reporters option to ON. However, when formatting the output suitable for printing, the program did not check the limit_reporters option and thus allowed reporters to see the summaries of bugs they did not report. Jeroen Latour discovered that the page responsible for displaying a list of bugs in a particular project, did not check whether the user actually has access to the project, which is transmitted by a cookie variable. It accidently trusted the fact that only projects accessible to the user were listed in the drop-down menu. This provides a malicious user with an opportunity to display the bugs of a private project selected. These problems have been fixed in version 0.17.1-2.2 for the current stable distribution (woody) and in version 0.17.4a-2 for the unstable distribution (sid). The old stable distribution (potato) is not affected, since it doesn't contain the mantis package. We recommend that you upgrade your mantis packages immediately. wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.
