Cisco and VMware have unveiled security updates to address critical security flaws in their goods that could be exploited by destructive actors to execute arbitrary code on influenced programs.
The most intense of the vulnerabilities is a command injection flaw in Cisco Industrial Network Director (CVE-2023-20036, CVSS score: 9.9), which resides in the web UI element and occurs as a consequence of incorrect enter validation when uploading a Unit Pack.
“A prosperous exploit could allow for the attacker to execute arbitrary commands as NT AUTHORITYSYSTEM on the underlying operating procedure of an influenced system,” Cisco stated in an advisory produced on April 19, 2023.
The networking machines big also settled a medium-severity file permissions vulnerability in the same product (CVE-2023-20039, CVSS rating: 5.5) that an authenticated, local attacker could abuse to perspective delicate facts.
Patches have been produced offered in edition 1.11.3, with Cisco crediting an unnamed “exterior” researcher for reporting the two issues.
Also preset by Cisco is a further critical flaw in the exterior authentication mechanism of the Modeling Labs network simulation system. Tracked as CVE-2023-20154 (CVSS rating: 9.1), the vulnerability could permit an unauthenticated, distant attacker to access the web interface with administrative privileges.
“To exploit this vulnerability, the attacker would require valid person qualifications that are stored on the associated external authentication server,” the enterprise noted.
“If the LDAP server is configured in such a way that it will reply to lookup queries with a non-vacant array of matching entries (replies that have research outcome reference entries), this authentication bypass vulnerability can be exploited.”
Whilst there are workarounds that plug the security gap, Cisco cautions consumers to exam the usefulness of these remediations in their very own environments prior to administering them. The shortcoming has been patched with the release of version 2.5.1.
VMware ships updates for Aria Functions for Logs
VMware, in an advisory released on April 20, 2023, warned of a critical deserialization flaw impacting many variations of Aria Functions for Logs (CVE-2023-20864, CVSS score: 9.8).

“An unauthenticated, destructive actor with network access to VMware Aria Operations for Logs could be capable to execute arbitrary code as root,” the virtualization expert services supplier reported.
VMware Aria Functions for Logs 8.12 fixes this vulnerability along with a higher-severity command injection flaw (CVE-2023-20865, CVSS score: 7.2) that could permit an attacker with admin privileges to run arbitrary instructions as root.
“CVE-2023-20864 is a critical issue and should really be patched immediately,” the firm reported. “It wants to be highlighted that only model 8.10.2 is impacted by this vulnerability.”
The inform comes pretty much 3 months after VMware plugged two critical issues in the same products (CVE-2022-31704 and CVE-2022-31706, CVSS scores: 9.8) that could result in distant code execution.
With Cisco and VMware appliances turning out to be rewarding targets for menace actors, it really is advisable that customers shift promptly to implement the updates to mitigate probable threats.
