IBM i Access Client Solutions 1.1.2.0 through 1.1.9.13 is vulnerable to arbitrary code execution on Windows when installed for all users due to publicly writeable directory.
AnalysisAI
Arbitrary code execution in IBM i Access Client Solutions 1.1.2.0 through 1.1.9.13 on Windows is enabled by a publicly writable directory created when the application is installed in 'all users' mode. A local attacker with low privileges can plant malicious content in this directory, which the application subsequently loads with higher-privilege context, achieving full code execution. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two concrete conditions to be simultaneously true: (1) IBM i Access Client Solutions must have been installed using the 'install for all users' mode on a Windows system - a per-user installation is not affected; and (2) the attacker must have an interactive local session or equivalent local code execution on the same Windows machine with at least low-privilege user rights (PR:L per CVSS). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) is consistent with the vulnerability mechanics: local access with low privileges is sufficient, no user interaction is needed, and the impact across all three pillars is high. … 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 | IBM has released a patch addressing this vulnerability; organizations should upgrade IBM i Access Client Solutions to the version specified in the vendor advisory at https://www.ibm.com/support/pages/node/7282954. … Detailed patch versions, workarounds, and compensating controls in full report. |
