Vulnerability Research Food Chain

I’ve mentioned the sociology aspect of the hacker, vuln researcher and security companies before, specifically how they interact, how one will influence another and more. The list of fun ideas I have on these topics is great, and maybe some day i’ll find the time to write more on them. In the mean time, this obvious one popped up and focuses on vulnerability researchers, how they find bugs, and how some feed off the work of others. We see this often where ResearcherA will find a vulnerability in one script, disclose the information, and ResearcherB will followup shortly after with the same type of vulnerability in a different script of the same product.

Recently we’ve seen a rash of remote file inclusion bugs in various add-ons to Mambo and Joomla. These add-ons are typically not written by the same developers nor are they distributed with the base installation of each product. However, they all seem to have one thing in common: “mosConfig_absolute_path” (or sometimes “absolute_path”). The same variable is being exploited in dozens of different add-ons and being found by different people. If we examine the chain of disclosure, can we see patterns in who consistently does followup research (low hanging fruit) instead of finding original vulnerabilities? Are there more observations in the way they are disclosed such as reporting to exploit sites vs Bugtraq or Full Disclosure? Are there misplaced signs of ego that accompany what amounts to trivial vulnerability finds while others are more modest and take it for what it is? Is it surprising that as people jump on the bandwagon, more and more reports end up being inaccurate and not a real vulnerability?

While skimming the list, strike-out text indicates the vulnerability has been disputed or proven false. The names of the researchers who didn’t fully check their find are in bold (and I’m curious if the other disclosures hold up under scrutiny). There is one occurrence of italics that potentially shows this type of “research” being used in the wild.
