New malformed Wi-Fi name bug can require iPhone factory reset to fix

• justshowpost 5y ago
  The description circulating the internets is very vague, involves some obscure personal(?) hotspot... Not going to torture my gadgets, but looks like saving networks with ESSID "%p%s%s%s%s%n" causing wifid to crash on WFLog:message Should also work with configuring network with such ESSID manually. The other sprintf specifiers in ESSID should work too. > factory reset Not that bad, Reset Network Settings fixes. https://blog.chichou.me/2021/06/20/quick-analysis-wifid/ https://blog.chichou.me/2021/06/20/quick-analysis-wifid/

    Read the article, That's the old one. He found a new one "%secretclub%power" that resetting network settings didn't fix.

      Current solution [1] seems to involve backing up your iPhone locally, removing the offending SSID from a plist (com.apple.wifi.plist?), and restoring your iPhone from that backup.

  re: exploitability – I think its still open question and highly depends on when WFLog logs ESSID...
