IBM Concert 1.0.0 through 3.0.0 could allow a remote authenticated attacker to cause a denial of service due to improper enforcement of storage limits.
AnalysisAI
An authenticated remote user of IBM Concert versions 1.0.0 through 3.0.0 can degrade or deny service availability by driving storage consumption past the limits the product is supposed to enforce. The vulnerability is rated CVSS 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H), meaning the attacker needs a valid account and network reachability to the Concert service but no user interaction; the only impacted security property is availability, with no confidentiality or integrity loss. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated session on IBM Concert (versions 1.0.0 through 3.0.0) with network reachability to the service (PR:L, AV:N, AC:L, UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a moderate-priority, availability-only issue best characterized as a genuine-but-bounded risk rather than an urgent one. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the vendor fix from IBM's advisory at https://www.ibm.com/support/pages/node/7288830 - patch availability is confirmed by the vendor, and administrators should consult that page for the exact corrected build or upgrade path applicable to their deployment rather than assuming a version number. … Detailed patch versions, workarounds, and compensating controls in full report. |
