The dissect_capwap_data function in epan/dissectors/packet-capwap.c in the CAPWAP dissector in Wireshark 1.6.x before 1.6.16 and 1.8.x before 1.8.8 incorrectly uses a -1 data value to represent an error condition, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

Detection & IOCsextracted from sources · hover to see the quote

port5247/UDP
  • Monitor for anomalously short (19-byte) UDP datagrams destined to port 5247 (CAPWAP data channel) that carry an incomplete CAPWAP payload, as this is the exploit delivery mechanism.
  • Affected Wireshark versions are 1.6.0–1.6.15 and 1.8.0–1.8.7; presence of these versions on a host receiving CAPWAP traffic on UDP/5247 indicates exposure.
  • ·The exploit only triggers the vulnerability if Wireshark is actively capturing/dissecting traffic on the interface receiving the crafted UDP packet; passive capture must be running for the crash to occur.
  • ·Red Hat Enterprise Linux 5 and 6 ship a version of Wireshark without CAPWAP dissector support and are therefore not affected, reducing the detection priority on those platforms.
