no, MKDIR is *not* required, also write access is *not* required. Assuming a directory with a name that starts with "A" exists and that is at least 14 chars long, this pattern will trigger the overflow: NLST [Ax206]*/../A*/../A*/../A*/../A*/../A*/../A*/../A*/\r\n At least on win2k3. Therefore, the workarounds for kb975191 on microsoft.com are wrong. Guido Landi Vladimir '3APA3A' Dubrovin wrote:
Dear Thierry Zoller, I think yes, MKDIR is required. It should be variation of S99-003/MS02-018. fuzzer should be very smart to create directory and user both oversized buffer and ../ in NLST - it makes path longer than MAX_PATH with existing directory. --Monday, August 31, 2009, 8:21:12 PM, you wrote to full-disclosure () lists grok org uk: TZ> Confirmed.
