{"vuid":"VU#914681","idnumber":"914681","name":"Mozilla Firefox fails to properly sanitize user-supplied URIs via shell script","keywords":["Mozilla","Firefox","arbitrary command execution","URL","command line","shell script","URI","external application"],"overview":"A lack of input validation in a supplemental shell script included with some Mozilla browsers may allow a remote, unauthenticated attacker to execute arbitrary commands.","clean_desc":"The Linux versions of the Mozilla Firefox and Mozilla Suite web browsers include a wrapper shell script for invoking the browser on URIs supplied by external applications. This shell script fails to sanitize shell metacharacters from the supplied URI parameters before using them to construct a shell command. By sending a specially crafted URI to a user of an application configured to invoke this shell script, a remote, unauthenticated attacker may be able to execute arbitrary commands on the vulnerable system. This issue only affects Linux systems using the supplied firefox or mozilla shell scripts or other Unix-like systems specifically configured to use these scripts.","impact":"A remote, unauthenticated attacker may be able to execute arbitrary commands with the privileges of the user of the application which invoked the vulnerable shell script.","resolution":"Upgrade The Mozilla project has released version 1.0.7 of the Firefox web browser which includes a patch for this issue. Firefox users are encouraged to upgrade to this version of the software. The Mozilla project has also released version 1.7.12 of the Mozilla Suite product which includes a patch for this issue. Mozilla Suite users are encouraged to upgrade to this version of the software.","workarounds":"Workarounds Do not click on URIs provided by external applications, such as email clients, on the affected systems. Copy and paste the URI into the browser instead.","sysaffected":"","thanks":"Thanks to \nPeter Zelezny \nfor reporting this vulnerability.","author":"This document was written by Chad R Dougherty.","public":["https://bugzilla.mozilla.org/show_bug.cgi?id=307185","http://secunia.com/advisories/16869/","http://secunia.com/advisories/16846/","http://secunia.com/advisories/16901/","http://www.auscert.org.au/5513"],"cveids":["CVE-2005-2968"],"certadvisory":"","uscerttechnicalalert":null,"datecreated":"2005-09-20T19:04:16Z","publicdate":"2005-09-20T00:00:00Z","datefirstpublished":"2005-09-22T20:34:19Z","dateupdated":"2005-12-22T20:05:52Z","revision":22,"vrda_d1_directreport":"","vrda_d1_population":"","vrda_d1_impact":"","cam_widelyknown":"20","cam_exploitation":"0","cam_internetinfrastructure":"7","cam_population":"10","cam_impact":"15","cam_easeofexploitation":"8","cam_attackeraccessrequired":"20","cam_scorecurrent":"12.15","cam_scorecurrentwidelyknown":"12.15","cam_scorecurrentwidelyknownexploited":"21.15","ipprotocol":"","cvss_accessvector":"","cvss_accesscomplexity":"","cvss_authentication":null,"cvss_confidentialityimpact":"","cvss_integrityimpact":"","cvss_availabilityimpact":"","cvss_exploitablity":null,"cvss_remediationlevel":"","cvss_reportconfidence":"","cvss_collateraldamagepotential":"","cvss_targetdistribution":"","cvss_securityrequirementscr":"","cvss_securityrequirementsir":"","cvss_securityrequirementsar":"","cvss_basescore":"","cvss_basevector":"","cvss_temporalscore":"","cvss_environmentalscore":"","cvss_environmentalvector":"","metric":12.15,"vulnote":null}
