CVE-2023-33850: IBM GSKit-Crypto information disclosure

HighCVSS 7.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 30/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.1% (FIRST EPSS); higher than 67.8% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: java-1_8_0-ibm (openSUSE:Leap 15.5) 1.8.0_sr8.20-150000.3.86.1; java-1_8_0-ibm (SUSE:Linux Enterprise Module for Legacy 15 SP5) 1.8.0_sr8.20-150000.3.86.1; java-1_8_0-ibm (SUSE:Linux Enterprise Software Development Kit 12 SP5) 1.8.0_sr8.20-30.120.1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to java-1_8_0-ibm (openSUSE:Leap 15.5) 1.8.0_sr8.20-150000.3.86.1; java-1_8_0-ibm (SUSE:Linux Enterprise Module for Legacy 15 SP5) 1.8.0_sr8.20-150000.3.86.1; java-1_8_0-ibm (SUSE:Linux Enterprise Software Development Kit 12 SP5) 1.8.0_sr8.20-30.120.1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

IBM GSKit-Crypto could allow a remote attacker to obtain sensitive information, caused by a timing-based side channel in the RSA Decryption implementation. By sending an overly large number of trial messages for decryption, an attacker could exploit this vulnerability to obtain sensitive information.
