Cisco warned on Wednesday that two unpatched vulnerabilities in its enterprise email security product, Secure Email, have been publicly disclosed. ^[1] On Wednesday, Cisco announced patches for multiple critical-severity security defects in IOS XR and Nexus 9000 series switches that could lead to remote code execution, authentication bypass, code injection, and other types of attacks. ^[2] Cisco Systems, a networking technology company, is generating hyperscaler AI infrastructure orders at a scale that would make pure-play networking rivals envious. ^[3] All Secure Email devices running AsyncOS version 16.5.0 or earlier with S/MIME enabled are affected by the vulnerabilities. ^[4] The two flaws, tracked as CVE-2026-20354 and CVE-2026-20355, are medium-severity issues affecting the Secure/Multipurpose Internet Mail Extensions (S/MIME) decryption functionality of the threat protection solution. ^[5] Cisco Systems' stock valuation still reflects that of a company primarily selling switches to office parks, rather than one with significant AI infrastructure growth. ^[6] The gap between Cisco's hyperscaler AI order numbers and its market valuation suggests that the stock is overlooked by investors. ^[7]
