Local file disclosure via re-enabled SAX entities
Published Jul 26, 2022 · Updated Aug 3, 2024
XML external entity injection in Christian Stefanescu untangle 1.2.0 and earlier allows remote attackers to read local files. The parse() entry point uses a standard SAX parser whose feature overrides can re-enable external general entities, causing system identifiers in crafted DTDs to resolve into parsed content. Any application that passes attacker-controlled XML to parse() exposes files readable by its process; exploitation requires a reachable integration but no authentication.
