Siemens Alert: Patch Now to Thwart RUGGEDCOM APE1808 Vulnerabilities!

Beware Siemens users: CISA’s ICS security advisories are so yesterday—like flip phones and privacy. For the freshest scoop on Siemens’ product vulnerabilities, it’s all about the Siemens’ ProductCERT now. Stay patched, stay secure, stay laughing at hackers trying to knock on outdated doors. #SiemensSecurityScoop

Hot Take:

It’s like Siemens has become the new Hogwarts for cybersecurity enthusiasts, except instead of learning spells, they’re casting patches to ward off the dark cyber arts. CISA’s latest advisory reads like the Marauder’s Map of vulnerabilities, showing us where the cyber-creeps are lurking. But fear not, dear netizens, for Siemens and CISA are on the case, wielding their cybersecurity wands and murmuring “Expelliarmus!” to disarm any potential network nasties.

Key Points:

  • Siemens RUGGEDCOM APE1808’s vulnerabilities could lead to a cyber rave without the glow sticks—reflected and amplified TCP denial-of-service (RDoS) attacks.
  • Vulnerabilities include everything but the kitchen cyber-sink: Network Amplification, Sensitive Info Exposure, File Path Manipulation, Cross-site Scripting, and Credential Leakage.
  • Siemens offers the digital equivalent of a flu shot—upgrades and patches—to keep your systems healthy against these bugs.
  • Protect your digital kingdom with moats and drawbridges: Siemens and CISA recommend minimizing network exposure and isolating control systems.
  • Cybercriminals haven’t RSVP’d to this vulnerability party yet, according to CISA—no active exploitation reports at the time of the advisory.
Title: PAN-OS: Plaintext Disclosure of External System Integration Credentials
Cve id: CVE-2023-6791
Cve state: PUBLISHED
Cve assigner short name: palo_alto
Cve date updated: 12/13/2023
Cve description: A credential disclosure vulnerability in Palo Alto Networks PAN-OS software enables an authenticated read-only administrator to obtain the plaintext credentials of stored external system integrations such as LDAP, SCP, RADIUS, TACACS+, and SNMP from the web interface.

Title: PAN-OS: DOM-Based Cross-Site Scripting (XSS) Vulnerability in the Web Interface
Cve id: CVE-2023-6790
Cve state: PUBLISHED
Cve assigner short name: palo_alto
Cve date updated: 12/13/2023
Cve description: A DOM-Based cross-site scripting (XSS) vulnerability in Palo Alto Networks PAN-OS software enables a remote attacker to execute a JavaScript payload in the context of an administrator’s browser when they view a specifically crafted link to the PAN-OS web interface.

Title: PAN-OS: Reflected Amplification Denial-of-Service (DoS) Vulnerability in URL Filtering
Cve id: CVE-2022-0028
Cve state: PUBLISHED
Cve assigner short name: palo_alto
Cve date updated: 08/10/2022
Cve description: A PAN-OS URL filtering policy misconfiguration could allow a network-based attacker to conduct reflected and amplified TCP denial-of-service (RDoS) attacks. The DoS attack would appear to originate from a Palo Alto Networks PA-Series (hardware), VM-Series (virtual) and CN-Series (container) firewall against an attacker-specified target. To be misused by an external attacker, the firewall configuration must have a URL filtering profile with one or more blocked categories assigned to a source zone that has an external facing interface. This configuration is not typical for URL filtering and, if set, is likely unintended by the administrator. If exploited, this issue would not impact the confidentiality, integrity, or availability of our products. However, the resulting denial-of-service (DoS) attack may help obfuscate the identity of the attacker and implicate the firewall as the source of the attack. We have taken prompt action to address this issue in our PAN-OS software. All software updates for this issue are expected to be released no later than the week of August 15, 2022. This issue does not impact Panorama M-Series or Panorama virtual appliances. This issue has been resolved for all Cloud NGFW and Prisma Access customers and no additional action is required from them.

Title: PAN-OS: Exposure of Sensitive Information Vulnerability
Cve id: CVE-2023-0005
Cve state: PUBLISHED
Cve assigner short name: palo_alto
Cve date updated: 04/12/2023
Cve description: A vulnerability in Palo Alto Networks PAN-OS software enables an authenticated administrator to expose the plaintext values of secrets stored in the device configuration and encrypted API keys.

Title: PAN-OS: Read System Files and Resources During Configuration Commit
Cve id: CVE-2023-38046
Cve state: PUBLISHED
Cve assigner short name: palo_alto
Cve date updated: 11/09/2023
Cve description: A vulnerability exists in Palo Alto Networks PAN-OS software that enables an authenticated administrator with the privilege to commit a specifically created configuration to read local files and resources from the system.

Title: PAN-OS: Local File Disclosure Vulnerability in the PAN-OS Web Interface
Cve id: CVE-2023-0008
Cve state: PUBLISHED
Cve assigner short name: palo_alto
Cve date updated: 05/11/2023
Cve description: A file disclosure vulnerability in Palo Alto Networks PAN-OS software enables an authenticated read-write administrator with access to the web interface to export local files from the firewall through a race condition.

The Sieve of Siemens

Siemens RUGGEDCOM APE1808 is waving its vulnerabilities like a kid showing off their bad report card. With a CVSS score of 6.1, it's not the end of the world, but it's not winning any cybersecurity awards either. We've got a guest list of vulnerabilities long enough to make any IT professional consider a career change to goat herding.

Attack of the Clones

These vulnerabilities could enable attackers to clone your network traffic and throw a massive RDoS party. Imagine someone photocopying flyers for a house party and distributing them to a whole city. The result? A party so big it blocks the street, except this time it's your network that's clogged.

The Patchwork Quilt

Siemens, playing the role of the digital grandma, has knitted together some patches and workarounds to keep your systems warm and safe. Upgrading to Palo Alto Networks Virtual NGFW V11.0.1 is like getting a new winter coat that actually fits.

Siege Warfare

Siemens and CISA are advocating for a medieval approach to cybersecurity—firewalls and isolation. Remember, your network is a castle, and you don't want the barbarians (hackers) storming the gates.

No RSVPs Yet

While the vulnerabilities are out there like a free buffet, no one has taken a bite—yet. CISA hasn't seen any active exploitation, but that's no reason to start live-streaming your firewall's vulnerabilities. Stay vigilant, patch up, and keep your digital shields up.
