Cisco Patches High-Severity Vulnerability in Security Solutions By Orbit Brain August 11, 2022 0 270 views Residence › VulnerabilitiesCisco Patches Excessive-Severity Vulnerability in Safety OptionsBy Ionut Arghire on August 11, 2022TweetCisco this week introduced the discharge of patches for a high-severity vulnerability in Adaptive Safety Equipment (ASA) and Firepower Menace Protection (FTD) software program that would enable an unauthenticated attacker to leak an RSA personal key.The ASA software program is the core working system of Cisco’s ASA safety gadgets, which offer safety to knowledge facilities and company networks, whereas the FTD software program delivers next-generation firewall providers.Tracked as CVE-2022-20866, the vulnerability exists due to “a logic error when the RSA secret is saved in reminiscence on a {hardware} platform that performs hardware-based cryptography,” Cisco notes in its advisory.A menace actor utilizing a Lenstra side-channel assault towards a susceptible gadget may exploit the safety bug to retrieve the RSA personal key.“This vulnerability will apply to roughly 5 % of the RSA keys on a tool that’s working a susceptible launch of Cisco ASA Software program or Cisco FTD Software program; not all RSA keys are anticipated to be affected on account of mathematical calculations utilized to the RSA key,” Cisco explains.The tech firm additionally notes {that a} legitimate RSA key could have particular traits making it susceptible to the leak, or could also be malformed and invalid, being created by a susceptible software program launch that created an invalid RSA signature – resulting in failed verification.In both case, an attacker could use the obtained RSA personal key to impersonate a tool working ASA or FTD software program, or to decrypt the gadget visitors.The vulnerability, Cisco explains, impacts the next ASA gadgets with FirePOWER providers: ASA 5506-X, ASA 5506H-X, ASA 5506W-X, ASA 5508-X, and ASA 5516-X, in addition to the Firepower 1000 collection next-gen firewalls, the Firepower 2100, 4100, and 9300 collection safety home equipment, and the Safe Firewall 3100 merchandise.Solely ASA software program releases 9.16.1 and later and FTD software program releases 7.0.Zero and later are impacted by this vulnerability. ASA software program releases 9.16.3.19, 9.17.1.13, and 9.18.2, and FTD software program releases 7.0.4, 7.1.0.2-2, and seven.2.0.1 deal with the safety flaw.“As the results of this vulnerability, Cisco ASA or FTD gadget directors could have to take away malformed or prone RSA keys and probably revoke any certificates related to these RSA keys. It is because it’s attainable the RSA personal key has been leaked to a malicious actor,” Cisco says.The tech firm additionally notes that info on this vulnerability has already been made public, however that it isn’t conscious of any exploitation makes an attempt.On Wednesday, Cisco additionally introduced patches for a request smuggling vulnerability within the Clientless SSL VPN (WebVPN) element of ASA software program, which may enable an unauthenticated, distant attacker to launch assaults from the browser, by tricking the sufferer into accessing a malicious web site.Cisco deprecated help for the susceptible element in ASA software program launch 9.17(1) and encourages prospects to improve to a non-vulnerable launch. As a attainable workaround, prospects may disable the Clientless SSL VPN characteristic, which may influence performance or efficiency.Tracked as CVE-2022-20713, the vulnerability is taken into account ‘medium severity’, however proof-of-concept exploit code concentrating on the bug is already out there publicly.In coordination with a Rapid7 discuss on the Black Hat 2022 convention in Las Vegas, Cisco additionally up to date a collection of beforehand printed advisories detailing high- and medium-severity vulnerabilities in ASA software program, Adaptive Safety Gadget Supervisor (ASDM), and FTD software program.A few of these vulnerabilities – comparable to CVE-2022-20651, CVE-2022-20828, and others – have already been addressed, however others have but to be correctly fastened, or they’ve but to obtain a patch in any respect.Rapid7 has printed a weblog publish detailing its findings.
