CVE-2021-32934 | ThroughTek P2P SDK - Cleartext Transmission of Sensitive Information

The affected ThroughTek P2P products (SDKs using versions before 3.1.5, any versions with nossl tag, device firmware not using AuthKey for IOTC conneciton, firmware using AVAPI module without enabling DTLS mechanism, and firmware using P2PTunnel or RDT module) do not sufficiently protect data transferred between the local device and ThroughTek servers. This can allow an attacker to access sensitive information, such as camera feeds.

Base score Version Severity Vector Exploitability Impact Score source
9.1 3.1 CRITICAL
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:N)
Service keeps running; no real outage angle.
