A CVE List V5 record names what it is about: a title such as "PAN-OS: Arbitrary File Creation Leads to OS Command Injection Vulnerability in GlobalProtect", a vendor and its products. None of it was kept, so a query for pan-os or prisma access only found records whose prose happened to say so. Every record now opens with the title in bold and a Vendor badge per affected vendor, refreshed from a local CVE List checkout in one pass and kept current by the daily sync for the records it fetches. Only the lines above the description move; descriptions and PoC sections are untouched. The pass also settled the heading link on cve.org and trimmed the stray space some version badges carried. The site index carries title, vendor and product for the 40 percent of indexed CVEs whose records have them. Search scores a hit in those above any position in the description, results show the title as a headline, and each page puts it under the CVE id, in the browser title, the meta description and an Affected row, with the block hubs listing it in place of the description's opening. The 35 MB metadata file the homepage needed before anything could be filtered is split in two for the page: the CVSS rows load with the rest, the advisories follow the index instead of competing with it for the connection. cve_metadata.json stays whole for anyone reading the API.

CVE-2017-6740
Description
The Simple Network Management Protocol (SNMP) subsystem of Cisco IOS and IOS XE Software contains multiple vulnerabilities that could allow an authenticated, remote attacker to remotely execute code on an affected system or cause an affected system to reload. An attacker could exploit these vulnerabilities by sending a crafted SNMP packet to an affected system via IPv4 or IPv6. Only traffic directed to an affected system can be used to exploit these vulnerabilities.
The vulnerabilities are due to a buffer overflow condition in the SNMP subsystem of the affected software. The vulnerabilities affect all versions of SNMP - Versions 1, 2c, and 3. To exploit these vulnerabilities via SNMP Version 2c or earlier, the attacker must know the SNMP read-only community string for the affected system. To exploit these vulnerabilities via SNMP Version 3, the attacker must have user credentials for the affected system. A successful exploit could allow the attacker to execute arbitrary code and obtain full control of the affected system or cause the affected system to reload.
Customers are advised to apply the workaround as contained in the Workarounds section below. Fixed software information is available via the Cisco IOS Software Checker. All devices that have enabled SNMP and have not explicitly excluded the affected MIBs or OIDs should be considered vulnerable.
There are workarounds that address these vulnerabilities.
