+Title:   EGI SVG 'ALERT' [TLP:CLEAR] Two BMC vulnerabilities (CVE-2023-34329)
+
+Date:    2023-07-27
+Updated: 
+
+Affected software and risk
+==========================
+
+The two security flaws enable attackers to bypass authentication or inject
+malicious code via Redfish remote management interfaces exposed to remote
+access: 
+
+CVE-2023-34329 - Authentication Bypass via HTTP Header Spoofing
+CVE-2023-34330 - Code injection via Dynamic Redfish Extension interface 
+
+See [R 1] [R 2] [R 3]
+
+The EGI SVG is aware that sites may use the remote management interface to
+ manage their deployments.  Both these vulnerabilities require adjacent or
+local network as well as high privileges in order to be exploited. If sites
+carry out best practice in their deployment  and ensure this service is only
+accessible to those who manage the site, it should not be possible to exploit
+these vulnerabilities.
+
+Actions required/recommended
+============================
+
+Sites running vulnerable servers should urgently apply vendor updates.
+
+Administrators should make sure that all remote server management interfaces
+such as Redfish and the BMC subsystems in their environments are not exposed
+externally. BMC interface access should be restricted to administrative users
+with Access Control Lists (ACL) in place.
+Disable default built-in administrative accounts that might be provided by the
+vendors, check if your vendor already provided a firmware upgrade that mitigates
+these vulnerabilities. A unique, well-protected admin account configuration for
+your management systems is usually a good practice.
+
+One case where sites may be vulnerable, is if Cloud users who have root access
+inside their VMs have unrestricted access to local networks and might thus be
+able to contact BMC endpoints. 
+
+If anyone becomes aware of any situation where this vulnerability has a
+significant impact on the EGI infrastructure then please inform EGI SVG.
+
+Component installation information
+==================================
+
+Sites should see information from their vendor.
+
+
+TLP and URL
+===========
+
+** CLEAR information - Unlimited distribution - see

+Comments
+========
+
+Comments or questions should be sent to svg-rat  at  mailman.egi.eu
+
+If you find or become aware of another vulnerability which is relevant to EGI
+you may report it by e-mail to
+
+report-vulnerability at egi.eu
+
+the EGI Software Vulnerability Group will take a look according to the
+procedure defined in [R 5]
+
+Note that this is undergoing revision to fully handle vulnerabilities in the
+EOSC era.

+
+2023-07-07 SVG alerted to this issue by Barbara Krasovec
+2023-07--- Investigation of vulnerability and relevance to EGI carried out
+2023-07-26 EGI SVG decided to send alert to sites, as a small number may be vulnerable.
+2023-07-27 Alert sent to sites
+
+
+Context
+=======
+
+This advisory has been prepared as part of the effort to fulfil EGI SVG's
+purpose "To minimize the risk to the EGI infrastructure arising from software
+vulnerabilities"
+
+The risk is that assessed by the group, according to the EGI SVG issue handling
+procedure [R 5] in the context of how the software is used in the EGI
+infrastructure. It is the opinion of the group, we do not guarantee it to be
+correct. The risk may also be higher or lower in other deployments depending on
+how the software is used.
+
+-----------------------------
+Others may re-use this information provided they:-
+
+1) Respect the provided TLP classification
+
+2) Credit the EGI https://www.egi.eu/ Software Vulnerability Group
+------------------------------
+
+Note that the SVG issue handling procedure is currently under review, to take
+account of the increasing inhomogeneity of the EGI infrastructure and the
+services in the EOSC catalogue.
