Vulnerabilities in this advisory

• CVE-2023-48795 — CVE-2023-48795 · CWE-222

  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 chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms. This also affects Maverick Synergy Java SSH API before 3.1.0-SNAPSHOT, Dropbear through 2022.83, Ssh before 5.1.1 in Erlang/OTP, PuTTY before 0.80, AsyncSSH before 2.14.2, golang.org/x/crypto before 0.17.0, libssh before 0.10.6, libssh2 through 1.11.0, Thorn Tech SFTP Gateway before 3.4.6, Tera Term before 5.1, Paramiko before 3.4.0, jsch before 0.2.15, SFTPGo before 2.5.6, Netgate pfSense Plus through 23.09.1, Netgate pfSense CE through 2.7.2, HPN-SSH through 18.2.0, ProFTPD before 1.3.8b (and before1.3.9rc2), ORYX CycloneSSH before 2.3.4, NetSarang XShell 7 before Build 0144, CrushFTP before 10.6.0, ConnectBot SSH library before 2.2.22, Apache MINA sshd through 2.11.0, sshj through 0.37.0, TinySSH through 20230101, trilead-ssh2 6401, the net-ssh gem 7.2.0 for Ruby, the mscdex ssh2 module before 1.15.0 for Node.js, the thrussh library before 0.35.1 for Rust, and the Russh crate before 0.40.2 for Rust; and there could be effects on Bitvise SSH through 9.31.

• CVE-2024-3596 — CVE-2024-3596 · CWE-924

  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.

• CVE-2024-5913 — CVE-2024-5913 · CWE-20

  An improper input validation vulnerability in Palo Alto Networks PAN-OS software enables an attacker with the ability to tamper with the physical file system to elevate privileges.

• CVE-2024-5920 — CVE-2024-5920 · CWE-79

  A cross-site scripting (XSS) vulnerability in Palo Alto Networks PAN-OS software enables an authenticated read-write Panorama administrator to push a specially crafted configuration to a PAN-OS node. This enables impersonation of a legitimate PAN-OS administrator who can perform restricted actions on the PAN-OS node after the execution of JavaScript in the legitimate PAN-OS administrator's browser.

• CVE-2024-9468 — CVE-2024-9468 · CWE-787

  A memory corruption vulnerability in Palo Alto Networks PAN-OS software allows an unauthenticated attacker to crash PAN-OS due to a crafted packet through the data plane, resulting in a denial of service (DoS) condition. Repeated attempts to trigger this condition will result in PAN-OS entering maintenance mode.

• CVE-2024-9471 — CVE-2024-9471 · CWE-20

  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.

• CVE-2025-0114 — CVE-2025-0114 · CWE-400

  A Denial of Service (DoS) vulnerability in the GlobalProtect feature of Palo Alto Networks PAN-OS software enables an unauthenticated attacker to render the service unavailable by sending a large number of specially crafted packets over a period of time. This issue affects both the GlobalProtect portal and the GlobalProtect gateway.

• CVE-2025-4231 — CVE-2025-4231 · CWE-77

  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.

• CVE-2025-4619 — CVE-2025-4619 · CWE-754

  A denial-of-service (DoS) vulnerability in Palo Alto Networks PAN-OS software enables an unauthenticated attacker to reboot a firewall by sending a specially crafted packet through the dataplane. Repeated attempts to initiate a reboot causes the firewall to enter maintenance mode.
