Abstract
U ovom radu dan je pregled najčešćih sigurnosnih problema u web hosting okruženjima, s fokusom na raširenu vrstu napada koji iskorištava ranjivosti u načinu na koji Apache web poslužitelj radi sa symlinkovima. Detaljno su obrazloženi: utjecaj ovakvih napada na poslužitelje koji koriste upravljačke ploče poput cPanela, ograničenja u prevenciji ovih napada, važnost brzine njihovog otkrivanja, i postupak mitigacije proizašle štete. Skripta foxhound.sh je izrađena s ciljem pravodobne detekcije ovih incidenata i jednostavne masovne implementacije na floti poslužitelja. Ova skripta traži symlinkove unutar početnih direktorija stranica na poslužitelju, vrši jednostavnu analizu rezultata i obavještava administratora ukoliko se incident dogodio. Također je izrađena skripta foxdie.sh, namijenjena automatizaciji procesa resetiranja zaporki za pristup bazama podataka kompromitiranih web aplikacija, zaporki njihovih administratorskih računa, te ažuriranju relevantnih konfiguracijskih datoteka. Korištenjem ove skripte uvelike se ubrzava postupak prevencije daljnjeg neovlaštenog pristupa kompromitiranim aplikacijama, te shodno tome i smanjuje šteta vlasnicima poslužitelja i stranica
Abstract (english)
This paper provides an overview of the most common security issues present in web hosting environments, with a focus on a widespread attack that exploits the way that the Apache web server handles symlinks. It provides a detailed explanation of how these attacks affect servers that utilize control panel software such as cPanel, the limitations of symlink attack prevention, the importance of quick detection of such attacks, as well as the process of mitigating the resulting damage. The foxhound.sh bash script was created with the goals of timely detection of such attacks and easy deployment on a fleet of servers. It searches for symlinks within the document roots of the websites present on the server, performs a simple analysis of the results, and notifies the administrator if an incident is found to have occurred. The foxdie.sh script was created to automate the process of resetting the database user and CMS administrator passwords of compromised sites, as well as updating the pertinent configuration files. Using this script greatly speeds up the process of preventing further unauthorized access to compromised sites, and thus also reduces the damage done to the owners of the server and sites.
