Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Code Injection

EUVDB-ID: #VU56308

Risk: Medium

CVSSv3.1: 8.1 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:U/RC:C]

CVE-ID: CVE-2021-28139

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to the Bluetooth Classic implementation does not properly restrict the Feature Page upon reception of an LMP Feature Response Extended packet. A remote attacker in radio range can use a specially crafted Extended Features bitfield payload and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Cybersecurity Help is currently unaware of any official solution to address this vulnerability.

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the local network (LAN).

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Buffer overflow

EUVDB-ID: #VU56310

Risk: Low

CVSSv3.1: 6 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:U/RC:C]

CVE-ID: CVE-2021-28136

CWE-ID: CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to the Bluetooth Classic implementation does not properly handle the reception of multiple LMP_IO_Capability_req packets during the pairing process. A remote attacker in radio range can send a specially crafted LMP packet, trigger memory corruption and cause a denial of service condition on the target system.

Mitigation

Cybersecurity Help is currently unaware of any official solution to address this vulnerability.

3) Input validation error

EUVDB-ID: #VU56311

Risk: Low

CVSSv3.1: 6 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:U/RC:C]

CVE-ID: CVE-2021-28135

CWE-ID: CWE-20 - Improper Input Validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to the Bluetooth Classic implementation does not properly handle the reception of continuous unsolicited LMP responses. A remote attacker in radio range can send LMP Feature Response data and perform a denial of service (DoS) attack.
