Summary

CVE-2023-1362 is a medium-severity Improper Restriction of Rendered UI Layers or Frames (CWE-1021) vulnerability in Bumsys Project Bumsys. Its CVSS base score is 6.1 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Drive-by Compromise (T1189); ranked in the top 29% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2023-1362 is an instance of improper restriction of rendered UI layers or frames, tracked as CWE-1021, that affects the unilogies/bumsys repository prior to version 2.0.2. The flaw received a CVSS 3.1 score of 6.1 with the vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N, indicating a network-reachable issue that requires user interaction and produces changed scope with limited confidentiality and integrity consequences.

An unauthenticated remote attacker can exploit the vulnerability by framing application pages inside an attacker-controlled site. When a victim interacts with the framed content, the attacker can overlay malicious UI elements to induce unintended actions, resulting in limited disclosure or modification of data within the affected bumsys instance.

Public references point to a fix merged in commit 8c5b27d54707f9805b27ef26ad741f2801e30e1f that resolves the frame-restriction issue; the associated huntr.dev report confirms the patch was accepted and the project was updated to 2.0.2.

The EPSS score reached a peak of 0.6930 after disclosure before settling at the current value of 0.5110, indicating a material rise in exploitation interest that warrants renewed attention.

prevents

Secure SDLC practices directly require implementing frame-ancestors / X-Frame-Options controls that prevent this weakness.

finds

Security testing can detect missing frame protections, but does not itself implement the control.

degrades

Web filtering can block or sandbox untrusted frames, but does not enforce application-level frame-busting or CSP.

prevents

Application security requirements can mandate frame-ancestors / X-Frame-Options, directly addressing UI redressing risks.

prevents

Secure architecture principles include isolation of UI layers and proper use of browser security controls.

prevents

Secure coding practices directly require implementation of frame-busting headers or CSP frame-ancestors directives.
