July 11, 2024 CISA ICS Advisory

Summary

Palo Alto Networks has published [1] information on vulnerabilities in PAN-OS. This advisory lists the related Siemens Industrial products affected by these vulnerabilities. Siemens is preparing updates and recommends specific countermeasures for products where updates are not, or not yet available. Customers are advised to consult and implement the workarounds provided in Palo Alto Networks' upstream security notifications. [1] https://security.paloaltonetworks.com/ CVE-2023-48795: The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in [email protected] and (if CBC is used) the [email protected] MAC algorithms.

Vulnerabilities as Stated by the Advisory

CVEWeaknessCVSS v3Details
CVE-2025-4231 CWE-77 Improper Neutralization of Special Elements used in a Command ('Command Injection') 9.1 Critical CVE-2025-4231
A command injection vulnerability in Palo Alto Networks PAN-OS® enables an authenticated administrative user to perform actions as the root user. The attacker must have network access to the management web interface and successfully authenticate to exploit this issue.

Mitigation: Configure the RADIUS server to require the presence of a Message-Authenticator attribute in all Access-Request packets from RADIUS client devices that support it

Mitigation: Customers can resolve this issue by configuring the in-use SSH profile to contain at least one cipher and at least one MAC algorithm, which removes support for CHACHA20-POLY1305 and all Encrypt-then-MAC algorithms available (ciphers with -etm in the name) in …

Mitigation: Exposure can be reduced by limiting access to the management interface to trusted internal IP addresses as described in Palo Alto Networks' Security Advisory

Affected, fixed & timeline

Affected:

  • RUGGEDCOM APE1808 all versions

Mitigation: Restrict access to the networks where RADIUS messages are exchanged (e.g., send RADIUS traffic via management network or a dedicated VLAN)

CVE-2024-3596 CWE-924 Improper Enforcement of Message Integrity During Transmission in a Communication Channel 9.0 Critical CVE-2024-3596
RADIUS Protocol under RFC 2865 is susceptible to forgery attacks by a local attacker who can modify responses Access-Reject or Access-Accept using a chosen-prefix collision attack against MD5 Response Authenticator signature.

Mitigation: Configure the RADIUS server to require the presence of a Message-Authenticator attribute in all Access-Request packets from RADIUS client devices that support it

Mitigation: Customers can resolve this issue by configuring the in-use SSH profile to contain at least one cipher and at least one MAC algorithm, which removes support for CHACHA20-POLY1305 and all Encrypt-then-MAC algorithms available (ciphers with -etm in the name) in …

CVE-2023-48795 CWE-222 Truncation of Security-relevant Information 5.9 Medium CVE-2023-48795
The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC).

A privilege escalation (PE) vulnerability in the XML API of Palo Alto Networks PAN-OS software enables an authenticated PAN-OS administrator with restricted privileges to use a compromised XML API key to perform actions as a higher privileged PAN-OS administrator. For example, an administrator with "Virtual system administrator (read-only)" access could use an XML API key of a "Virtual system administrator" to perform write operations on the virtual system configuration even though they should be limited to read-only operations.

Mitigation: Configure the RADIUS server to require the presence of a Message-Authenticator attribute in all Access-Request packets from RADIUS client devices that support it

Mitigation: Customers can resolve this issue by configuring the in-use SSH profile to contain at least one cipher and at least one MAC algorithm, which removes support for CHACHA20-POLY1305 and all Encrypt-then-MAC algorithms available (ciphers with -etm in the name) in …
