CVE-2024-45751
tgt (aka Linux target framework) before 1.0.93 attempts to achieve entropy by calling rand without srand. The PRNG seed is always 1, and thus the sequence of challenges is always identical.
02 Description
tgt (aka Linux target framework) before 1.0.93 attempts to achieve entropy by calling rand without srand. The PRNG seed is always 1, and thus the sequence of challenges is always identical.
03 Exploitation and scoring
- Exploitation
- Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
- SSVC decision
- ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
- AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
- Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
- EPSS probability
- 0.54% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 45.6% of scored records. A rank, not a probability.
- NVD base score
- 5.9 (CVSS v3.x), scored by the NVD independently of the CNA.
- NVD CVSS vector
- CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N
- NVD analysis status
- Deferred. NVD last modified this record on 2026-06-17.
