Cisco launched patches to handle a number of vulnerabilities within the Cisco Expressway Sequence which may enable an attacker to do arbitrary operations on a susceptible system.
Cisco Expressway Sequence contains Cisco Expressway Management (Expressway-C) and Cisco Expressway Edge (Expressway-E) units.
“A number of vulnerabilities within the Cisco Expressway Sequence might enable an unauthenticated, distant attacker to conduct cross-site request forgery (CSRF) assaults, which might enable the attacker to carry out arbitrary actions on an affected system,” Cisco stated.
An attacker could induce customers into performing actions they don’t intend to by utilizing an online safety flaw referred to as cross-site request forgery, or CSRF.
Cisco patched the CSRF vulnerabilities recognized as CVE-2024-20252 and CVE-2024-20254 (CVSS rating: 9.6) with ‘vital’ severity and CVE-2024-20255 (CVSS rating: 8.2) with ‘excessive’ severity rankings.

Cisco Expressway Sequence CSRF
CVE-2024-20252 and CVE-2024-20254
An unauthorized distant attacker could possibly launch CSRF assaults towards a compromised system on account of two vulnerabilities within the API of Cisco Expressway Sequence units.
“These vulnerabilities are on account of inadequate CSRF protections for the web-based administration interface of an affected system. An attacker might exploit these vulnerabilities by persuading a person of the API to comply with a crafted hyperlink”, Cisco stated.
A profitable vulnerability might enable the attacker to do arbitrary actions with the susceptible person’s privileges. These actions might contain altering the system configuration and making new privileged accounts if the impacted person has administrative capabilities.
CVE-2024-20255
Cisco Expressway Sequence API vulnerability could allow a distant, unauthenticated attacker to launch a CSRF assault towards a compromised system.
This vulnerability outcomes from inadequate CSRF protections for a susceptible system’s web-based administration interface. An attacker might exploit this vulnerability by convincing an API person to click on on a specifically crafted hyperlink.
“A profitable exploit might enable the attacker to carry out arbitrary actions with the privilege stage of the affected person. If the affected person has administrative privileges, these actions might embody overwriting system configuration settings, which might stop the system from processing calls correctly and lead to a denial of service (DoS) situation”, Cisco stated.
Affected Merchandise
CVE-2024-20254 and CVE-2024-20255 impression Cisco Expressway Sequence units when they’re configured by default.
CVE-2024-20252: This vulnerability impacts Cisco Expressway Sequence units if the cluster database (CDB) API function is enabled. By default, this function isn’t enabled.
Fixes Launched
| Cisco Expressway Sequence Launch | First Fastened Launch |
|---|---|
| Sooner than 14.0 | Migrate to a hard and fast launch. |
| 14.0 | 14.3.4 |
| 15.0 | 15.0.0 |
On account of its end-of-support date, the Cisco Expressway Sequence now not covers the Cisco TelePresence Video Communication Server (VCS).
Cisco has not printed software program upgrades for Cisco TelePresence VCS to repair the vulnerabilities, and it’ll not launch any sooner or later.
Unified Communications Supervisor (CM) and Contact Middle Options merchandise are affected by a vital severity distant code execution weak point that Cisco introduced in January. This lets the attackers run the command as a root person.
It is strongly recommended that customers improve to the newest model to stop these vulnerabilities from getting exploited.
