4 known affected

The vendor explicitly identifies these products as affected by this CVE.

  • Desigo DXR2
  • Desigo PXC3
  • Desigo PXC4
  • Desigo PXC5
Summary
The application, after a successful login, sets the session cookie on the browser via client-side JavaScript code, without applying any security attributes (such as “Secure”, “HttpOnly”, or “SameSite”). Any attempts to browse the application via unencrypted HTTP protocol would lead to the transmission of all his/her session cookies in plaintext through the network. An attacker could then be able to sniff the network and capture sensitive information.
Remediation
Update to V01.21.142.5-22 or later version. Please contact your local Siemens office for additional support in obtaining the update.

What, why and how

A vulnerability has been identified in Desigo DXR2 (All versions < V01.21.142.5-22), Desigo PXC3 (All versions < V01.21.142.4-18), Desigo PXC4 (All versions < V02.20.142.10-10884), Desigo PXC5 (All versions < V02.20.142.10-10884). The application, after a successful login, sets the session cookie on the browser via client-side JavaScript code, without applying any security attributes (such as “Secure”, “HttpOnly”, or “SameSite”). Any attempts to browse the application via unencrypted HTTP protocol would lead to the transmission of all his/her session cookies in plaintext through the network. An attacker could then be able to sniff the network and capture sensitive information.

Any attempts to browse the application via unencrypted HTTP protocol would lead to the transmission of all his/her session cookies in plaintext through the network. An attacker could then be able to sniff the network and capture sensitive information.

Why

The Secure attribute for sensitive cookies in HTTPS sessions is not set.

How

An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may obtain information outside the intended access boundary.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
a network path → Sensitive Cookie in HTTPS Session Without 'Secure' Attribute → obtain information outside the intended access boundary
Attack surface
Network
Privileges required
Low: a basic authenticated account is required

Low: no specialised conditions are recorded
Security boundary

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-614 ↗

CWE-614: Sensitive Cookie in HTTPS Session Without 'Secure' Attribute. The Secure attribute for sensitive cookies in HTTPS sessions is not set.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

AVNetworkAttack vector: The vulnerable component can be reached over a network.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRLowPrivileges required: The attacker needs basic user-level privileges.UINoneUser interaction: No action by another user is required.SUnchangedScope: The security impact remains within the vulnerable component's authority.CHighConfidentiality impact: A successful attack can cause a major loss.INoneIntegrity impact: No direct loss is represented by this metric.ANoneAvailability impact: No direct loss is represented by this metric.
Post-exploitation / living off the land
No specific living-off-the-land technique is confirmed in the structured sources. Monitor normal administration tools for activity inconsistent with the affected service's baseline.
