Oracle Application Express: URL Redirection to Untrusted Site

Published Updated By the CyberSecBulletin desk

CVE-2025-50067 is a critical-severity URL redirection to untrusted site vulnerability in Oracle Application Express from Oracle, with a CVSS 3.1 base score of 9.0 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. Affected Oracle Application Express versions: 24.2.4; 24.2.5. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.34% chance of exploitation within 30 days, which is low compared with other CVEs.

Critical severity: a successful attack would have severe impact.

What to do

  1. Check which version of Oracle Application Express you run against the affected versions below, and install the vendor's latest release.
  2. Read the advisory on oracle.com for workarounds and exact fixed builds.
  3. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description

Vulnerability in Oracle Application Express (component: Strategic Planner Starter App). Supported versions that are affected are 24.2.4 and 24.2.5. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Application Express. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Application Express, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle Application Express. CVSS 3.1 Base Score 9.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H).

The underlying weakness: URL Redirection to Untrusted Site

The web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect.

How developers prevent this class of flaw

  • Use an intermediate disclaimer page that provides the user with a clear warning that they are leaving the current site. Implement a long timeout before the redirect occurs, or force the user to click on the link. Be careful to avoid XSS problems (CWE-79) when generating the disclaimer page.
  • When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs. For example, ID 1 could map to /login.asp and ID 2 could map to http://www.example.com/. Features such as the ESAPI AccessReferenceMap provide this capability.
  • Ensure that no externally-supplied requests are honored by requiring that all redirect requests include a unique nonce generated by the application. Be sure that the nonce is not predictable (CWE-330).
