Colossal Intel Update Anchored by Critical Privilege-Escalation Bugs

  • Intel released 40 security advisories in full, addressing critical- and higher-severity flaws across its Energetic Management Technology, Wi-fi Bluetooth and NUC merchandise.

    A huge Intel security update this thirty day period addresses flaws throughout a myriad of merchandise – most notably, critical bugs that can be exploited by unauthenticated cybercriminals in get to obtain escalated privileges.

    These critical flaws exist in goods connected to Wi-fi Bluetooth – like various Intel Wi-Fi modules and wi-fi network adapters – as very well as in its distant out-of-band management device, Energetic Administration Technology (AMT).

    Over-all, Intel produced 40 security advisories on Tuesday, every addressing critical-, significant- and medium-severity vulnerabilities across different items. That by much trumps October’s Intel security update, which resolved one high-severity flaw in BlueZ, the Linux Bluetooth protocol stack that supplies aid for core Bluetooth levels and protocols to Linux-dependent internet-of-factors (IoT) devices.

    Critical Flaws

    Just one critical-severity vulnerability exists in Intel AMT and Intel Normal Manageability (ISM). AMT, which is utilized for distant out-of-band administration of PCs, is portion of the Intel vPro platform (Intel’s umbrella internet marketing time period for its collection of personal computer components technologies) and is generally used by organization IT shops for distant administration of corporate techniques. ISM has a similar operate as AMT.

    The flaw (CVE-2020-8752) which ranks 9.4 out of 10 on the CvSS vulnerability-severity scale, stems from an out-of-bounds generate mistake in IPv6 subsystem for Intel AMT and Intel ISM. If exploited, the flaw could enable an unauthenticated consumer to attain escalated privileges (through network entry).

    Versions right before 11.8.80, 11.12.80, 11.22.80, 12..70 and 14..45 are influenced consumers are urged to “update to the hottest edition presented by the technique producer that addresses these issues.”

    One more critical-severity flaw (CVE-2020-12321) exists in some Intel Wireless Bluetooth goods just before version 21.110. That bug, which scores 9.6 out of 10 on the CvSS scale, could allow an unauthenticated consumer to potentially allow escalation of privilege by means of adjacent accessibility. This implies an attacker is essential to have accessibility to a shared actual physical network with the victim.

    Influenced solutions consist of Intel Wi-Fi 6 AX200 and AX201, Intel Wi-fi-AC 9560, 9462, 9461 and 9260, Intel Twin Band Wi-fi-AC 8265, 8260 and 3168, Intel Wi-fi 7265 (Rev D) family members and Intel Dual Band Wi-fi-AC 3165. Users of these goods are recommended to update to edition 21.110 or later on.

    Superior-Severity Flaws

    Intel also fixed many substantial-severity vulnerabilities, like a path traversal in its Endpoint Management Assistant (CVE-2020-12315) — which offers equipment to check and enhance units. This flaw could give an unauthenticated consumer escalated privileges by way of network obtain.

    4 high-severity flaws exist in Intel PROSet/Wi-fi Wi-Fi solutions ahead of version 21.110. Intel PROSet/Wi-fi Wi-Fi software is employed to established up, edit and handle Wi-Fi network profiles to hook up to Wi-Fi networks.

    These vulnerabilities stem from insufficient regulate-stream administration (CVE-2020-12313), incorrect input validation (CVE-2020-12314), security-mechanism failure (CVE-2020-12318) and incorrect buffer restriction (CVE-2020-12317). They can help denial-of-company (DoS) attacks or privilege escalation.

    A different significant-severity flaw in Intel strong-point out generate (SSD) products could allow for an unauthenticated user to most likely allow info disclosure – if they have actual physical entry to the system. The flaw (CVE-2020-12309) stems from insufficiently guarded credentials in the consumer SSD subsystems. A selection of SSDs – such as the Pro 6000p collection, Pro 5450s and E 5100s collection – are affected and can be uncovered below.

    Intel’s Subsequent Unit Computing (NUC) mini Personal computer also experienced two superior-severity flaws together with an insecure default variable initialization issue in the firmware (CVE-2020-12336), that could let authenticated people (with regional entry) to escalate their privileges. The other is an incorrect buffer restriction in the firmware (CVE-2020-12337) enabling privileged buyers to escalate privileges (through regional entry).

    Other superior-severity flaws contain an poor buffer restriction (CVE-2020-12325) in Intel Thunderbolt DCH drivers for Windows an improper obtain-handle hole (CVE-2020-12350) in Intel’s Serious Tuning Utility and an incorrect enter-validation flaw (CVE-2020-12347) in the Intel Data Middle Supervisor Console.
