Affected: Bitnami: harbor

A timing condition in Harbor 2.6.x and below, Harbor 2.7.2 and below,  Harbor 2.8.2 and below, and Harbor 1.10.17 and below allows an attacker with network access to create jobs/stop job tasks and retrieve job task information.

A timing condition in Harbor 2.6.x and below, Harbor 2.7.2 and below,  Harbor 2.8.2 and below, and Harbor 1.10.17 and below allows an attacker with network access to create jobs/stop job tasks and retrieve job task information.

Affected: Go: github.com/goharbor/harbor

In the Harbor jobservice container, the comparison of secrets in the authenticator type is prone to timing attacks. The vulnerability occurs due to the following code: https://github.com/goharbor/harbor/blob/aaea068cceb4063ab89313d9785f2b40f35b0d63/src/jobservice/api/authenticator.go#L69-L69 To avoid this issue, constant time comparison should be used. ``` subtle.ConstantTimeCompare([]byte(expectedSecret), []byte(secret)) == 0 ```

### Impact This attack might be possible theoretically, but no workable proof of concept is available, and access complexity is set at High. The jobservice exposes these APIs ``` Create a job task --- POST /api/v1/jobs Get job task information --- GET /api/v1/jobs/{job_id} Stop job task --- POST /api/v1/jobs/{job_id} Get job log task --- GET /api/v1/jobs/{job_id}/log Get job execution --- GET /api/v1/jobs/{job_id}/executions Get job stats --- GET /api/v1/stats Get job service configuration --- GET /api/v1/config ``` It is used to create jobs/stop job tasks and retrieve job task information. If an attacker obtains the secrets, it is possible to retrieve the job information, create a job, or stop a job task.

The following versions of Harbor are involved: <=Harbor 2.8.2, <=Harbor 2.7.2, <= Harbor 2.6.x, <=Harbor 1.10.17

### Patches Harbor 2.8.3, Harbor 2.7.3, Harbor 1.10.18

### Workarounds Because the jobservice only exposes HTTP service to harbor-core containers, blocking any inbound traffic from the external network to the jobservice…
