CWE-1022 vulnerabilities

CVE-2025-27902 is a medium severity vulnerability in IBM DB2 Recovery Expert for Linux, UNIX and Windows version 5.5 IF 2. It involves the use of a web link to an untrusted external target with window.opener access, which could allow a remote attacker to expose sensitive information or perform unauthorized actions in the victim's web browser.

PILOS, a frontend for BigBlueButton, versions from 2.1.0 up to but not including 4.14.1, does not set the Cross-Origin-Opener-Policy header. This allows pages opened with target="_blank" to retain a window.opener reference, enabling reverse tabnabbing attacks where a malicious page can manipulate the original PILOS tab. The issue is fixed in version 4.14.1.

SAP Fiori (Launchpad) is vulnerable to Reverse Tabnabbing vulnerability due to inadequate external navigation protections for its link (<a>) elements. An attacker with administrative user privileges could exploit this by leveraging compromised or malicious pages. While administrative access is necessary for certain configurations, the attacker does not need the administrative privileges to execute the attack. This could result in unintended manipulation of user sessions or exposure of sensitive information. The issue impacts the confidentiality and integrity of the system, but the availability remains unaffected.

IBM Sterling B2B Integrator and IBM Sterling File Gateway 6.0.0.0 through 6.1.2.7 and 6.2.0.0 through 6.2.0.4 uses a web link with untrusted references to an external site. A remote attacker could exploit this vulnerability to expose sensitive information or perform unauthorized actions on the victims’ web browser.
