SICAM T: Cleartext Transmission of Sensitive Information
CVE-2022-29874 is a high-severity cleartext transmission of sensitive information vulnerability in SICAM T from Siemens, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version V3.0 as the first without the flaw, so updating SICAM T to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.75% chance of exploitation within 30 days, higher than 56% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update SICAM T to V3.0 or a later version.
- Update 7kg8500-0aa00-0aa0 Firmware to 3.00 or a later version.
- Update 7kg8500-0aa00-2aa0 Firmware to 3.00 or a later version.
- Read the advisory on cert-portal.siemens.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
A vulnerability has been identified in SICAM T (All versions < V3.0). Affected devices do not encrypt web traffic with clients but communicate in cleartext via HTTP. This could allow an unauthenticated attacker to capture the traffic and interfere with the functionality of the device.

The underlying weakness: Cleartext Transmission of Sensitive Information
The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.
How developers prevent this class of flaw
- Before transmitting, encrypt the data using reliable, confidentiality-protecting cryptographic protocols.
- When using web applications with SSL, use SSL for the entire session from login to logout, not just for the initial login page.
- When designing hardware platforms, ensure that approved encryption algorithms (such as those recommended by NIST) protect paths from security critical data to trusted user applications.
