Abis Technology AVESIS Update Fixes Open Redirect
Tech GuruQuick Answer
TR-CERT identifies an unauthenticated open redirect in AVESIS builds from 202608201331 up to, but excluding, 202608240351. An open redirect can send a user from the legitimate application to an untrusted destination; it is not, by itself, evidence of account takeover or server code execution. Confirm the deployed build with the service owner and obtain the supported correction for that installation.
Confirm Scope And Apply The Supported Fix
What to do now: Inventory Abis Technology AVESIS builds from 202608201331 before 202608240351, match the exact affected release or feature, apply the authority-supported fixed build or service remediation, validate the dependent workflow, and preserve evidence.
Source recheck: October 2, 2026 UTC, against the TR-CERT CVE record. The public affected interval is source-checked; a specific vendor package and deployed redirect behavior were not tested.
Scope And Authority
| Product scope | Abis Technology AVESIS builds from 202608201331 before 202608240351 |

| Authority revision date | 2026-09-23 14:37:54.686 UTC |
| Affected versions | Abis Technology AVESIS builds from 202608201331 before 202608240351 |
| Fixed version | AVESIS build 202608240351 or later |
| CVSS base score | 5.4 (CVSS v3.1) |
| CVSS severity | Medium |
| Exploitation status | Not stated by the authority; no exploitation claim is inferred. |
What Changed
The advisory's CVSS vector requires user interaction and does not require an attacker account. Keep those conditions distinct from the impact: the public record names redirection to an untrusted site but does not disclose a specific endpoint, parameter or observed credential theft.
What To Validate Now
- Inventory. Record the full AVESIS build identifier, hosting/service owner and any application links or redirects used in the affected workflow. Do not shorten the build identifier into an assumed date or semantic version.
- Establish applicability. Compare each deployment with the authority's affected-version statement: Abis Technology AVESIS builds from 202608201331 before 202608240351 Do not infer applicability from product family or severity alone.
- Remediate. Apply AVESIS build 202608240351 or later through the supported vendor or project channel, following the current advisory and change-control requirements.
- Validate. On an authorized staging instance, confirm that normal internal redirects work and unapproved destinations are rejected using a benign test destination. Do not collect real credentials or run a phishing exercise to validate the patch.
- Retain evidence. Preserve asset and owner identifiers, the applicability decision, before-and-after versions, change approval, installation output, validation results, and any exception or rollback record.
Operational Cautions
Use the exact supported release stream and repository. Test dependencies, clusters, integrations, and rollback before broad deployment; a CVSS rating or reachable feature is not evidence of exploitation.
Evidence To Retain
- Exact product, release stream, package or application version, enabled feature, environment, and accountable owner.
- UTC timestamps, authority revision, approved change record, installer or package-manager output, and resulting version.
- Relevant logs and monitoring evidence, test results, exceptions, compensating controls, and rollback decisions.
