Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Integer underflow
EUVDB-ID: #VU19580
Risk: High
CVSSv3.1: 8.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2019-12255
CWE-ID:
CWE-191 - Integer underflow
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer underflow when processing TCP packets with URG-flag set. A remote attacker can send a specially crafted TCP request to the affected system, trigger integer underflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Vulnerable software versionsPowerConnect Series: before 5.1.16.1
External linksQ & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
2) Race condition
EUVDB-ID: #VU19583
Risk: Low
CVSSv3.1: 5.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-12263
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform denial of service (DoS) attack.
The vulnerability exists due to a race condition when processing TCP packets. A remote unauthenticated attacker can send malicious sequence of TCP packets within a specific timing, trigger a race condition and perform denial of service attack.

3) Input validation error
EUVDB-ID: #VU19584
Risk: Low
CVSSv3.1: 4 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L/E:F/RL:O/RC:C]
CVE-ID: CVE-2019-12258
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation when processing options in TCP packets. A remote attacker can a specially crafted TCP packet with the source and destination TCP-port and IP-addresses of an existing session can reset the TCP session, leading to a DoS attack.
