CVE-2017-5833 Revive Adserver CVE debrief

CVE-2017-5833 is a cross-site scripting issue in Revive Adserver’s invocation code generation for interstitial zones. According to the NVD record, versions through 4.0.0 are affected, and the vendor advisory identifies a fix in 4.0.1. The flaw can let a remote attacker inject arbitrary web script or HTML through unspecified parameters, which can affect confidentiality and integrity in browser contexts where the generated code is rendered or reused.

Who should care

Operators and developers running Revive Adserver before 4.0.1, especially sites that use interstitial zones or expose invocation-code generation features to users, editors, or administrators. Security teams should also care if ad-serving code is embedded into pages that may be viewed by multiple users.

Technical summary

The official records describe a CWE-79 cross-site scripting condition in Revive Adserver. NVD lists the vulnerable CPE as Revive Adserver versions up to and including 4.0.0, with CVSS 3.0 vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N. The issue is described as affecting invocation code generation for interstitial zones, where remote attackers can inject arbitrary script or HTML via unspecified parameters. The vendor advisory is linked as the patch reference, indicating remediation in 4.0.1.

Defensive priority

Medium. The issue is network-reachable and does not require privileges, but it does require user interaction and the impact is limited to confidentiality and integrity in the browser context. Prioritize if your deployment uses interstitial zones or distributes generated invocation code broadly.

Recommended defensive actions

  • Upgrade Revive Adserver to version 4.0.1 or later.
  • Review any workflows that generate or display interstitial zone invocation code and treat all user-controlled inputs as untrusted.
  • Validate that generated HTML and script snippets are properly encoded or sanitized before rendering.
  • If immediate upgrade is not possible, restrict access to ad-management interfaces and limit who can generate or edit invocation code.
  • Check for any stored or reflected XSS indicators in custom integrations around interstitial zone code generation.

Evidence notes

The NVD record classifies this as CWE-79 and lists affected versions through 4.0.0, with CVSS 3.0 AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N. The published description states the flaw is in invocation code generation for interstitial zones and that remote attackers can inject arbitrary web script or HTML via unspecified parameters. The vendor advisory reference points to a patch in Revive Adserver 4.0.1. Openwall and SecurityFocus are included in the reference set as corroborating third-party references.
