--------- End Update A Part 2 of 4 ---------
--------- Begin Update A Part 3 of 4 ---------
Dahua ASI7XXX allows users to upload a promotional picture or video displayed when device is in standby, which may allow an attacker to upload unvalidated files other than a picture or a video, such as an executable file; this could lead to a denial-of-service.
CVE-2022-30560 has been assigned to this vulnerability. A CVSS v3 base score of 7.6 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:H).
Dahua ASI7XXX is vulnerable to Pass the Hash of a captured authentication hash, which could allow an attacker to sniff the authentication process and access the device without needing a password.
CVE-2022-30561 has been assigned to this vulnerability. A CVSS v3 base score of 5.9 has been assigned; the CVSS vector string is (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N).
Dahua ASI7XXX is vulnerable when an unknown username is entered; the web server returns a valid username in an error message. This could allow an attacker to gain valid username values to use in authentication attacks.
CVE-2022-30562 has been assigned to this vulnerability. A CVSS v3 base score of 3.7 has been assigned; the CVSS vector string is (AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N).
Dahua ASI7XXX is vulnerable to an authentication replay in the ONVIF web interaction. An attacker capable of sniffing the network traffic could replay the authentication data and access the device as the captured authenticated user.
CVE-2022-30563 has been assigned to this vulnerability. A CVSS v3 base score of 6.8 has been assigned; the CVSS vector string is (AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N).
