CVE-2022-50689: Cobian Reflector 0.9.93 RC1 Local Denial of Service via Password Field

Cobian Reflector 0.9.93 RC1 contains a denial of service vulnerability that allows attackers to crash the application by overflowing the password input field. Attackers can paste a large 8000-byte buffer into the password field to trigger an application crash during SFTP task configuration.

Security readout for executives and security teams

Plain-English summary

CVE-2022-50689 is a local denial-of-service issue in Cobian Reflector 0.9.93 RC1. A user with access to the application can crash it through the password field during SFTP task configuration. This does not indicate data theft or remote compromise, but it can disrupt backup operations on affected systems.

Executive priority

Treat as a moderate operational-risk issue. Prioritize systems where Cobian Reflector supports important backups or recovery workflows. The urgency is higher if untrusted users can access the application locally.

Technical view

The vulnerability is reported as CWE-120 in Cobian Reflector 0.9.93 RC1. The application can crash when processing an overly long password value in SFTP task configuration. CVSS v4.0 is 6.9 with local attack vector, low complexity, no privileges required, and high vulnerable-system availability impact.

Likely exposure

Exposure is limited to systems running Cobian Reflector 0.9.93 RC1 where a local user can interact with the application. The main business risk is interruption of backup configuration or backup application availability, not network-wide compromise.

Exploitation context

The source bundle includes an ExploitDB reference, indicating public exploit information exists. CISA KEV status is false in the provided data, and no cited source states active exploitation in the wild.

Researcher notes

Evidence supports a local application crash through password-field input handling. Sources do not name a vendor patch or fixed version. Avoid assuming broader impact beyond availability loss for Cobian Reflector 0.9.93 RC1 unless additional vendor evidence appears.

Mitigation direction

  • Identify whether Cobian Reflector 0.9.93 RC1 is installed.
  • Check Cobian Software guidance for fixed versions or vendor-recommended workarounds.
  • Restrict local interactive access to systems running affected versions.
  • Avoid using release-candidate software for critical backup workflows where possible.
  • Monitor backup job failures and application crashes on affected hosts.

Validation and detection

  • Inventory endpoints and servers for Cobian Reflector installations.
  • Confirm installed version and whether it is 0.9.93 RC1.
  • Review whether SFTP task configuration is used.
  • Check Windows application logs for Cobian Reflector crashes.
  • Validate remediation against vendor documentation before production rollout.
