The U.S. Cybersecurity and Infrastructure Safety Company (CISA) has added two six-year-old safety flaws impacting Sitecore CMS and Expertise Platform (XP) to its Identified Exploited Vulnerabilities (KEV) catalog, primarily based on proof of energetic exploitation.
The vulnerabilities are listed beneath –
- CVE-2019-9874 (CVSS rating: 9.8) – A deserialization vulnerability within the Sitecore.Safety.AntiCSRF module that permits an unauthenticated attacker to execute arbitrary code by sending a serialized .NET object within the HTTP POST parameter __CSRFTOKEN
- CVE-2019-9875 (CVSS rating: 8.8) – A deserialization vulnerability within the Sitecore.Safety.AntiCSRF module that permits an authenticated attacker to execute arbitrary code by sending a serialized .NET object within the HTTP POST parameter __CSRFTOKEN
There are at present no particulars on how the issues are being weaponized within the wild and by whom, though SiteCore in an replace shared on March 30, 2020, said it grew to become “conscious of energetic exploitation” of CVE-2019-9874. The corporate makes no mention of CVE-2019-9875 being exploited.
In mild of energetic exploitation, federal businesses are required to use the mandatory patches by April 16, 2025, to safe their networks.
The event comes as Akamai mentioned it has noticed preliminary exploit makes an attempt probing potential servers for a newly disclosed safety flaw impacting the Subsequent.js internet framework (CVE‑2025‑29927, CVSS rating: 9.1).
An authorization bypass vulnerability, a profitable exploitation may allow an attacker to get round middleware-based safety checks by spoofing a header known as “x‑middleware‑subrequest” that is used to handle inner request flows. This, in flip, may allow unauthorized entry to delicate software sources, Checkmarx’s Raphael Silva said.
“Among the many recognized payloads, one notable method entails utilizing the x-middleware-request header with the worth src/middleware:src/middleware:src/middleware:src/middleware:src/middleware,” the online infrastructure firm said.
“This method simulates a number of inner subrequests inside a single request, triggering Subsequent.js’s inner redirect logic — intently resembling a number of publicly out there proof-of-concept exploits.”
The disclosures additionally observe a warning from GreyNoise about energetic exploitation makes an attempt recorded in opposition to a number of recognized vulnerabilities in DrayTek units.
The risk intelligence agency mentioned it has seen noticed in-the-wild exercise in opposition to the beneath CVE identifiers –
- CVE-2020-8515 (CVSS rating: 9.8) — An working system command injection vulnerability in a number of DrayTek router fashions that might permit distant code execution as root by way of shell metacharacters to the cgi-bin/mainfunction.cgi URI
- CVE-2021-20123 (CVSS rating: 7.5) — An area file inclusion vulnerability in DrayTek VigorConnect that might permit an unauthenticated attacker to obtain arbitrary information from the underlying working system with root privileges by way of the DownloadFileServlet endpoint
- CVE-2021-20124 (CVSS rating: 7.5) — An area file inclusion vulnerability in DrayTek VigorConnect that might permit an unauthenticated attacker to obtain arbitrary information from the underlying working system with root privileges by way of the WebServlet endpoint
Indonesia, Hong Kong, and america have emerged as the highest vacation spot international locations of the assault visitors for CVE-2020-8515, whereas Lithuania, america, and Singapore have been singled out as a part of assaults exploiting CVE-2021-20123 and CVE-2021-20124.
